DataVault Unlocked: QR Codes

Did you know that some banknotes have QR codes? A QR (quick-response) code is a two-dimensional (2D) matrix barcode consisting of black and white squares that stores encoded data, such as website URLs, text or contact information. When a user scans the QR code, which can be done using a smartphone, they gain access to information about the currency, the issuing institution, or the commemorative events celebrated in the design.
