QR codes were developed in the 1990s to manage car parts – today they are by far the best way to link mobile phones to almost anything. In many applications QR codes are cheaper, easier, more flexible and more secure than RFID and NFC.
The European Central Bank (based in Frankfurt) manages the EURO, is one of the world’s most important central banks, and uses QR-codes to link traditional PC-webpages to mobile pages.
