9. QR CODE / QRC / 2D BARCODES


QR or Quick Response Codes are a type of two-dimensional(matrix) barcode that can be read using smartphones and dedicated QR reading devices, that link directly to text, emails, websites, phone numbers and more. Below is the QR code of visionias.in


QR codes are huge in Japan and across the East, and are slowly beginning to become commonplace in the West.

Ordinarily we think of a barcode as a collection of vertical lines; 2D Barcodes or QR Codes are different in that the data is stored in both directions and can be scanned vertically OR horizontally.

Whilst a standard 1D Barcode stores up to 30 numbers, a QR Barcode can store up to a massive 7,089! It is this massive amount of data that enables links to such things as videos, Facebook or Twitter pages or a plethora of other website pages.
