how to choose a good barcode scanner

January 21, 2019

It seems to uninformed buyers that if there is an inscription “for EGAIS” on the scanner, then this is a device with unique functionality and it is only possible to work with it in the Unified State Automated Information System. Ignorance of consumers is used by unscrupulous manufacturers, raising prices for specific models and using the sticker “for EGAIS” as an excuse to increase the final cost of the goods.

In this article, we will answer the main questions that entrepreneurs face when buying scanners from manufacturers to work with EGAIS:

  1. Why do we need 2D scanners for EGAIS?
  2. How do they differ from conventional devices with a 2D and 1D barcode reader?
  3. How to choose a scanner for EGAIS yourself?


A scanner for EGAIS is a scanning device with a reader that recognizes two-dimensional bar codes. At first, such models were used to obtain information from excise stamps on alcoholic products. Mandatory labeling of alcoholic beverages began several years ago and is still in use today. For each unit of goods, the manufacturer applies a unique two-dimensional code, which is read using a special scanner.

In 2019, mandatory labeling of tobacco products is introduced in Russia, and in the future, all goods in circulation in the Russian Federation will face such a fate. The new law will affect all market participants from manufacturers to retail outlets.

In addition to enterprises working with labeled products, two-dimensional signs are printed on tickets, price tags, documents and parts for high-tech production.

What is the difference between a 2D barcode scanner and a linear scanner?

The first is equipped with a reader of two types: 1D and 2D, the second recognizes only one-dimensional coding. Therefore, if for work you need to scan labels from alcohol brands or packs of cigarettes, then you need to purchase a 2D scanner.

The Unified State Automated Information System (EGAIS) is mandatory for implementation at all enterprises selling labeled products. Failure to connect is a serious violation, for which you can get an impressive fine.

How do 2D scanners for EGAIS differ from the usual ones?

The device for EGAIS is a simple 2D scanner at the checkout or warehouse with a PDF417 or DataMatrix code reader. Barcodes for excise stamps and packs of cigarettes, respectively. Choosing a model with two-dimensional code reading technology from the manufacturer, you automatically purchase a device suitable for working in the EGAIS system. There are no other specific requirements. When deciding which form factor or connection interface to choose, you buy from the manufacturer the product that is most suitable for solving the business problems of a particular enterprise.

How to choose a barcode scanner for EGAIS yourself?

Scanners that read 2D barcodes PDF 417, DataMatrix, EAN-8, EAN-13 and others are widely represented on the market by domestic and foreign manufacturers. The range of prices and specifications is wide. Based on many years of experience in selling scanners for EGAIS, Scanberry online store specialists recommend paying attention to the following points:

  • Form factor

    The first thing to decide is the type of scanner. It can be manual or stationary. It is believed that a handheld scanner for EGAIS is more suitable for working in warehouses, but it is also found at the checkouts of retail stores. When buying, pay attention to the length of the cable. As a rule, the length does not exceed 1.5 meters. If you plan to work with bulky goods that are difficult to bring to the scanner for EGAIS, it is better to choose a wireless model. Stationary options will facilitate and speed up work at the checkout. Built-in or stand-alone devices free the salesperson's hands, increasing the speed of customer service. Another option is a combined EGAIS code scanner. This is a hand-held device that comes with a special stand, which can be purchased separately.

  • Connection interface

    The second point that you need to pay attention to before buying a scanner with a 2D reader from the manufacturer is the connection interface. The scanner can be connected to other equipment using an RS-232 (COM port), KB (PS/2) or USB cable. The first option is more reliable. The wire is tightly connected to the POS system and the data is transferred to the trading program at the checkout, however, there is not always a free connector of this type. An easy-to-connect KB (PS / 2) cannot always ensure communication stability. The USB connection option guarantees a stable connection, and finding an unoccupied connector of this type is quite easy. In EGAIS wireless scanners, data is transmitted via Bluetooth, Wi-Fi or a radio channel.

How to choose a scanner

  • IP degree of protection

    Depending on the place of use and the operating conditions of the scanner for EGAIS, an important indicator is the degree of protection of the device. To serve customers at the checkout of the store, models with low IP30 or IP40 protection are used, but for dusty, humid and cool warehouses, you should look at devices with increased protection parameters.

Popular 2D code scanners for EGAIS

A good 2D barcode scanner for EGAIS should accurately read encoded information at maximum speed from any, even worn and damaged surfaces. Many models work not only with paper, but also electronic media, using modern image scanning technology.


  1. Scanner reader works with erased small codes up to 20 cm away.
  2. The reader processes information from convex surfaces.
  3. EGAIS scanners with image scanning technology are characterized by high reading speed

The Scanberry online store has a separate section where scanners for EGAIS from domestic and foreign manufacturers are collected. They are suitable for work in warehouses and cash desks of shops. These are high-quality and reliable devices with which you can automate business processes in accordance with the law.

TOP-5 scanners for work with the unified state automated system:

3D scanner for $30 We can do the same with a special program, a laser pointer and a webcam.

Only thirty dollars.

About 3D scanning

Many spheres of our life are inconceivable without three-dimensional graphics. A huge army of 3D modelers (or simply 3D’s) create models every day, which are then successfully used in a variety of areas, ranging from cinema, advertising, industrial production, architecture, and ending with God knows what else. Any person involved in modeling, sooner or later, faces the following task: you need to create a model of what already exists in our three-dimensional world. It could be anything. For example, a prototype model that a customer put on your desk and asked to do “exactly the same, only on a computer.” Moreover, it is necessary to model not just so that it “looks like”, but so that the prototype object and the three-dimensional model are like twin brothers separated by a computer screen. It happened to me as well. While completing another modeling order, I faced very strict requirements for matching my model to the client's sample. After the nth unsuccessful coordination, it became clear that this time the absolute accuracy of the model is needed. In any case, the client was sure that otherwise, if Armageddon did not come for all mankind, then at least something similar would happen. What was left for me to do? Finally try 3D scanning! I then thought: "This is modeling for the lazy." A minute of work - and that's it, the model is ready! To my great surprise (and disappointment), it turned out that even the simplest 3D scanner costs a lot of money. Or rather, very large. To buy it, I had to multiply the cost of this model by a number with five zeros. But if you can not buy, then we will do it ourselves. Below I want to share with you the experience of how to assemble a 3D scanner with your own hands. I will not only tell you what components and where to buy for this, but also how to use this scanner.

What do we need?

As it turned out, you can literally make your own 3D scanner from improvised materials: we need a special program, a laser pointer, a webcam, and some homemade devices.

Special software. The most important part of a scanner, including an expensive professional scanner, is its brain - the software that performs the digitization. What we need are tools that allow you to scan / digitize 3D objects with the help of available tools: webcams and a laser pointer. These are DAVID-laserscanner and TriAngles, available for free testing, but with some limitations. The latter has a rather unpleasant limitation: for its operation, a uniformly rotating table is required, on which the scanned object will be located. In addition, severe requirements are imposed on the object itself. Its shape should be close to cylindrical, and even better - spherical. DAVID-laserscanner does not have such requirements, so I chose it. Despite the fact that the program is paid and its cost ranges from 199 to 229 euros, you can test it for as long as you like - there are no time limits. The only limitation lies in the features of saving scan results. You can save scans, but in low quality. However, miracles sometimes happen on the Web, and if you manage to find a version of DAVID that saves in high quality, then you will save on this too. And whoever seeks will always find.

Webcam. The program reads the object's parameters necessary for creating the object using a webcam. You may have it. If so, great, you can try to crank everything with her. The main thing is that the resolution is at least 640 x 480. There are other requirements: manual focusing (the ability to turn off autofocus), a minimum of noise at high resolution, a high-quality camera lens - the lens should not give strong distortion. The camera must be connected to a USB port and work on WDM drivers (that is, simply speaking, it must be visible for selection in the DAVID program). Most modern webcams meet these requirements, but only you and I can check their compatibility with DAVID, so we will trust the recommendations of the program's creators to avoid any surprises. Of the cheap cameras, the developer himself recommends the Logitech WebCam Pro 9000 with cam holder, which can be bought for a hundred dollars. I have successfully scanned my $35 Logitech C270.

Setting up the scanner

Laser module. The scanner requires a component that will give a line. It's a line, not a dot. It is important! I read on the forums that a regular Chinese laser pointer would do, but it doesn't. No matter how fast you move your hand armed with a laser pointer, it's not the same. A little later I will explain why. Now one thing is important - you need a scanner that gives a line. Red, green, blue - the color of the scanner is unimportant. In general, you can do without a scanner, using alternative solutions (read in the sidebar). But the laser module is definitely the easiest and most affordable option. I purchased a 650nm red laser module with a 5mW line focus for $25. You can buy this one anywhere, for example, in a hardware store or via the Internet, as I did (I think at www.greenlaser.com.ua). I do not recommend purchasing modules of higher power (up to 20 mW), since their use is advisable in very rare cases. There are ready-made self-powered modules - if you find it, then buy one better. For my laser module, I had to create a small tool to make it convenient to hold in my hand, turn it on / off. I fed him with the usual crown 9B: red wire "+", black "-": if it is the other way around, it will heat up and, as a result, will fail prematurely.

Calibration angle. Orientation in space, being able to read the image parameters, allows the program a special device - the calibration angle. Fear not, this is the cheapest component, which is two sheets of specially applied markers that need to be placed at an angle of 90 °. After installing DAVID, you will find PDF or CDR files in the root directory, for example “Calibpoints_Scale30_DIN_A4.pdf”. Or with a similar name, but in CDR format for printing from CorelDraw. Select the file whose name corresponds to the size of the paper on which you are going to print. In general, I advise you to proceed from the size of the scanned object. Don't make a big angle if you're going to scan small objects. For starters, A4 size calibration sheets are quite suitable. It is more difficult to fix them at the right angle. I made my first corner like this - I simply bent the white corrugated cardboard, fixed it on the base, and then attached the calibration sheets butt-to-butt. It is better not to glue them, as the sheets will become wavy - this is unacceptable. Instead, you can carefully attach them around the edges with tape. I must say that after the very first scans, it became clear that the angle was not ideal. Therefore, I had to redo everything: I connected two pieces of chipboard, fastening them with corners. Turned out good: corner 90°, the surface is perfectly flat – all of which could not be achieved with corrugated board. In short, there are many options.

Scanning: with and without light

Creating a model

Now the most interesting thing - we proceed to the scanning process itself. Take a look around: there will probably be some souvenirs or figurines in the room - any small object will do for experiments. What definitely does not work is transparent or translucent objects. The laser beam should be reflected, not absorbed by objects. The creators of DAVID recommend in such cases to cover objects with talcum powder or, if you don't mind, with spray paint. I did not bother myself and took a few figurines. Conventionally, four stages can be distinguished in the scanning process, I will tell you about each in more detail.

Stage 1. Calibration. This is a preliminary stage, so the object to be scanned is set aside for now. Fix the webcam against the calibration corner so that all components are stationary relative to each other. The camera should be positioned at the level of the lower edge of the calibration sheets. The image must be bright during camera calibration. I scanned in the evening or during the day, but with a shaded window, and the calibration angle was illuminated by artificial light. The calibration itself is carried out in the DAVID-laserscanner. We select our webcam from the list of devices, adjust the image: increase the brightness, contrast. As a result, only black markers are visible on the screen. Click the "Calibrate Camera" button. If everything is done correctly, the program will congratulate you that the calibration was successful. Otherwise, you can try to change the position of the webcam, play around with brightness and contrast. I did not succeed the first time, but then the joy was like after the first handed session!

Stage 2. Placement of the object. To scan, place the object in the corner of the calibration corner. For best results, it should be approximately in the middle of the calibration sheets. If its dimensions are small, you can use a stand: a box, books, a wooden block of a suitable size. Tell the program the type of laser you are using. Let's turn off the lights! The screen should be dark. If not, lower the brightness values. Do not be afraid if the markers are not visible: the program has memorized their location, and now they are not so important to us. Turn on the laser and aim it at an angle just above our subject. A broken white line should appear on the screen (the program analyzes a black and white image). The distance between the camera and the laser plane (i.e. the triangulation angle) should be as large as possible for greater accuracy. Otherwise, you will see a warning: "Crossing angle is too small." At the beginning of the article, I talked you out of using a point laser pointer, and here's why. Even moving quickly with a dotted pointer, not only will you not get a straight line, but the program will not be able to calculate the value of the triangulation angle.

Stage 3. Scanning. The scanning process starts after pressing the "Start" button. It is necessary to draw the beam up and down on the object several times so that the program reads the parameters of the object through the webcam. There is an important point here: you need to turn the brush with the laser, and not lower your hand! Speed ​​is not important, but don't try to do it very fast. When scanning, I often looked not at the object, but at the screen, watching how the program analyzes the shape of the object, drawing colored lines on the screen. Looking at the screen is more convenient for two reasons. Firstly, if the laser line is not visible on both sides of the object or the triangulation angle is insufficient, the program will immediately display a message (and you can fix it). Secondly, looking at the laser is tiring for the eyes due to the high contrast between the black background and the bright beam. Having passed through the object with a beam up and down as much as necessary, press the "Pause" button. Now you can save the scan result to a separate file using the "Save" button. There is another option - immediately transfer the image for subsequent stitching with other scans by clicking the "Transfer" button. When you click "Transfer", the scan is transferred to the next stage (gluing) without saving to a file, but we do not leave the current stage and can repeat the scan by changing the position of the object (do not forget to press the "Delete" button before a new scan). It is important to understand here: to create a model, you need to make several scans. For simple objects, it will be enough for you to rotate the object, for example, by 45º. If the surface of the object is complex, then you will need to scan it from different sides and only then stitch the scans together. Another important point: the scans must necessarily overlap each other to make it easier for the program to analyze them.

4th stage. Form stitching. The last step before getting the model is merging the scans. If you did not save the scans, but transferred them for gluing using the appropriate button, then you can start stapling right away. Otherwise, click the "Add" button and load the previously saved files. The stitching process can be divided into two stages: scan joining and stitching itself. By selecting scans in pairs, you indicate to the program the joining method. DAVID copes with this very well, provided that there is something to join - the scans must overlap each other. If the patches do not overlap, you will have to go back to the previous step and scan from those positions of the object that will give such an overlap. Having completed the docking for all scans, click on the "Sew" button. Depending on the selected settings, in a few seconds we will see the result of stitching all the scans into a single model. Click the "Save" button. Now we can load our model into ZBrush or Mudbox and bring it to perfection. The model is ready!
In the TriAngles program, due to the rotation of the object, the formation of the digitized surface would occur automatically, this is its advantage over DAVID. But how would she cope with the formation of the surface in the "dead" zones? I don't think so. Or in these places we would get an error. We wanted to get the model as accurate as possible. Therefore, we will consider additional steps for stitching scans as necessary costs.

Finalizing the finished model in the 3D editor

Instead of a conclusion

It is quite possible to assemble a 3D scanner that will produce more than decent results at home. I hope you can verify this. Unfortunately, to scan small objects (and I needed to create objects for jewelry) you need a very good USB camera with a CCD matrix, which I don’t have (it’s quite expensive), so my experience remained experience: apply it on case for scanning jewelry did not work. But I experienced an unforgettable pleasure, getting full-fledged models of a variety of objects using a scanner that was assembled literally on my knee.

A homemade 3D scanner can get a good result

If there is no laser

You can do without a laser to 3D scan an object (I'm not kidding). A projector with a powerful lamp is suitable, the light of which must be directed through a narrow slit to the object being scanned. We get a narrow white line - why not a white laser? True, in addition to the projector (which is not cheap in itself), you also need serious equipment to hold the projector in the right position. It's hemorrhoids.
