QR Codes

QR Codes standard for Quick Response code and are also known as 2D barcodes. 1D barcodes are the typical linear code you will have seen everywhere. QR codes are becoming more popular as they can contain much more information than a standard 1D barcode. Many applications can now generate QR codes on your mobile phone for use with access control devices so as to avoid the need (and cost) for creating a physical credential.
