Barcode scan module

Types of barcode scan module

A barcode scan module helps to read various types of barcodes. Barcode modules are made up of different types of components, which include the scanning element, decoding hardware, and communications interface. The scanning element is the part of the module that moves along the barcode to read it. Scanning elements usually have photographs or lasers to make precise scans. After the scan, the data is then passed through the decoding hardware, which converts it into digital format. The digital information can then be transmitted to a computer or device for further processing. The kind of barcode scanning module used will depend on the type of barcode and the application. Barcode scan modules can be classified according to the types of barcodes they read, namely linear, 2D, and RFID.

• Linear barcode scan modules

  Linear barcodes are also known as 1D barcodes, and they have a single row of bars and spaces that are either vertical or horizontal. They include UPC, EAN, Code128, and Code39. Linear barcodes can be found on retail products, documents, and inventory items, among others. The linear barcode scan module is capable of reading and decoding linear barcodes without any difficulty.

• 2D barcode scan modules

  For more data to be stored, a 2D barcode is needed. It has two-dimensional codes, so it can be scanned vertically and horizontally. QR codes, Data Matrix, and PDF417 are examples of 2D barcodes. 2D barcodes can be printed on labels, displayed on mobile devices, or embossed on documents. The barcode scanning module can read various 2D barcodes in different formats. This makes it easy to integrate into applications for services like mobile payments, product authentication, and ticketing.

• RFID scan modules

  Radio frequency identification (RFID) modules are different from barcode scanners as they work with electromagnetic fields. An RFID scanner has a coupler that can transmit radio waves and a decoder to receive the data. In between is a signal processing unit that can identify and decode the information. RFID has tags with integrated circuits and antennas that can be read. Modules like the RFID scan module can read and decode information from different RFID tags. They are commonly used in supply chain management, asset tracking, and access control.

On the other hand, those with an IP67 rating are completely dust-tight and protected against submersion in water up to one meter for half an hour. Scan modules with IP65 and IP67 ratings are suitable for use in harsh environments.

• Reading Depth Range

  The reading depth range is the distance between the scanner and the barcode. It varies depending on the barcode type. For instance, the reading depth range for a 1D barcode might be between 0.039 inches and 3.93 inches. A 2D barcode might have a reading depth range of between 0.98 inches and 10 inches. Scanning modules with varied reading depth range can decode different barcodes with ease.

• Laser Pointer

  Some scanning modules have a laser pointer. Unfortunately, it is only compatible with laser-enabled scan engines. The pointer improves aim accuracy when scanning barcodes that have small text or are in tight spaces.
