Certain mobile apps claim to verify an Aadhaar card using a QR code scanner. However, the QR code is not a secure representation of an Aadhaar card either and can be copied and edited. The only way to validate an Aadhaar card is to perform an online validation, which will confirm that the card number is valid, and confirm the postal code and ...
The Barcode Scanner can automatically search the Web to identify a product with a barcode and use, for example, price-comparison information between vendors. The application can decode several 2D barcodes including the widely used QR Code and Data Matrix. QR codes are often embedded in websites; Barcode Scanner can open a browser at the encoded ...
The QR code system was invented in 1994, at the Denso Wave automotive products company, in Japan. [6] [7] [8] The initial alternating-square design presented by the team of researchers, headed by Masahiro Hara, was influenced by the black counters and the white counters played on a Go board; [9] the pattern of the position detection markers was determined by finding the least-used sequence of ...
Data encoder. A code is a set of symbols or signals that usually represent alphanumeric characters. When data are encoded, the characters are translated into machine-readable code. A label or tag containing the encoded data is attached to the item that is to be identified. Machine reader or scanner.

Each state in Brazil is allowed to print its own ID card, but the layout and data are the same for all of them. The ID cards printed in Rio de Janeiro are fully digitized using a 2D bar code with information which can be matched against its owner off-line. The 2D bar code encodes a color photo, a signature, two fingerprints, and other citizen ...
