Barcode readers and scanners
Barcode and QR code readers and scanners are easy-to-use devices used to automate the process of identifying people and objects using a barcode or multidimensional code (QR, AZTEC, Datamatrix), which is read by the scanner. Such a code can contain a string of characters that, properly assigned in a database, can inform about the name, type and price of a product or convey messages about a specific person who has his code assigned.
Code scanner - what is it?
Barcode scanner is a reliable and easy-to-use device used to automate the process of identifying people and objects by reading data from codes. The reader allows not only to read, but also to decode and transmit the information contained in the scanned code. Due to their simplicity and convenience, readers have their uses in almost every industry and enterprise, from simple office work to sales and service outlets. HDWR offers both barcode readers and QR code scanner (QR, PDF-417, Aztec)..
Barcode reader - how does it work?
The code scanner sends out a beam of light that hits the barcode, and here the light is reflected from the gaps between the black bars of the barcode. The reflected light returns to the scanner and falls on the mirror, which then directs such a beam to the photodetector located on the motherboard. Such a code can contain a string of characters, which, appropriately assigned in the database, can inform about the name, type and price of the product or transmit messages about a specific person who has his code assigned. In our store you will find both wired and wireless readers.
QR code reader - a sign of modernity
The Barcode Reader is a smart solution for your business that uses innovative image recognition systems even from unreadable, damaged and dirty surfaces. The wireless code reader and scanner allows you to work within a range of tens or even hundreds of meters from the transmission base. Many models also offer their user a storage mode. After reading the appropriate code from the instructions, the scanner can be used at any distance from the base, and all scanned codes will be stored in the device's internal memory. Fast reading speed, lightweight handles, powerful batteries - these are advantages that affect the convenience of use.QR code scanner - key advantages
QR code readers have the ability to convert a graphical QR code into digital form. QR codes can encode quite a large amount of data - up to 7089 numeric characters, 4296 alphanumeric. They usually have as a scanning module - a camera. What is most important for users is that the modern optics module can also cope with blurred, fuzzy or damaged codes. A great advantage of the reader is the ability to program any character as prefix and suffix, including function keys (F11, F9, F7, etc.). QR code reader comes in wired and wireless versions.
QR reader - read from the screen
QR readers have a built-in scanning chip made of high quality components, which enables fast and precise reading of leading barcodes, and QR (multidimensional) codes. Due to its wide application and automation of many business fields, barcode reader is very popular in all market segments. Moreover, many models have the ability to read codes both printed and displayed on LCD screens and displays. The scanning engine reads barcodes and QR codes, even if they are inverted, damaged, covered with a protective layer or displayed on a smartphone screen at the lowest brightness level.A barcode scanner will not read QR codes, while it works the other way, any QR code scanner will also read barcodes.What could be the applications of a QR code reader?
As of May 20, 2019, the EU TPD Tobacco Directive took effect, the tobacco industry had to adapt to the new regulations. As a result, it was necessary to procure new software, as well as to replace equipment designed to scan barcodes and QR codes. The directive, which came into force on the aforementioned date, was aimed at eliminating the process of counterfeiting tobacco products and preventing their illegal circulation. A new unique code called Dotcode. was created specifically for the purposes of the directive in question. Dotcode, is a two-dimensional code in graphical form, designed in such a way that its complexity thwarts attempts to falsify it. The code encapsulates such information as serial number, identifier of place and time of production. In addition to the Dotcode symbol, a less complicated DataMatrix code can be found on tobacco products, which has the same information encoded on it..
Dotcode is a complex code and not every barcode scanner can cope with reading it. Therefore, when looking for a scanner for the tobacco industry, an advanced scanning chip that offers to read the code created for the tobacco directive should be the main and most important factor, determining the purchase.What are the types of barcode readers?
There are many different models of barcode and QR code scanners available on the market, offering the widest variety of functions and designed for different applications. Considering the communication of the scanner with the target device, we can divide scanners into wired scanners and wireless scanners. Wired scanners work after connecting them to the USB port of the target device using a dedicated cable included in the set. Wireless readers, on the other hand, to work properly with the target device, can useradio communication via a USB receiver, or aBluetooth module, which provides an additional possibility of connection scanner with any mobile device. This solution gives you the freedom to work without disturbing cables. Please note that radio communication offers a much greater wireless range than the Bluetooth module. A further division that we can make regarding barcode and QR readers is into automatic, manual and stationary readers. Automatic scanners offer barcode scanning automatically, without the need to press the scanning button, and often come with a stand that offers almost maintenance-free use of the device. However,hand-held code readersrequire the use of a scanning button to read a barcode. Stationary readers, on the other hand, are wired readers intended for stationary operation. They feature a small, compact shape that helps save work space and are ideal for use in boutiques and small shops. Of course, a very important distinction is the division into one-dimensional 1D readers, i.e. those that read the most popular barcodes in the form of black and white stripes, andtwo-dimensional 2D scanners, which, in addition to the codes, barcodes, are able to scan codes in the form of graphic symbols, for example QR code. Additionally, barcode and QR code scanners may have useful functions such as storage mode or scanning codes from LCD screens and mobile device displays. Storage mode allows you to save a large number of read codes in the device's built-in memory for later transfer to a computer. In turn, readers that have a scanning system equipped with a CCD matrix in the case of 1D codes, or a CMOS matrix in the case of 2D codes, offer trouble-free reading of barcodes and QR codes displayed on LCD screens.
