Two of which are 2D barcodes, similar to QR codes, and RAIN RFID. When combined and supported by industry standards, the technologies may be the secret sauce to the next generation of self-check.

QR Codes are a two-dimensional type of matrix barcode that are used for a variety of uses. They’re one way of turning a long piece of string data into an easily machine-readable format.

Other kinds of barcode soon followed and the UPC also laid the foundations for so-called "2D barcodes" such as QR codes, which can encode even more information. But the history of these little ...

Barcode scanners read imprinted bar/matrix code symbologies. Barcodes, also known as universal product codes (UPCs), are machine-readable data representations consisting of a series of contrasting ...
