Good to see NFC and QR codes working together:
Key2Share allows virtual keys stored on NFC phones to be shared securely using QR codes that can be sent by email or MMS message — or even in the mail.
KEY2SHARE: “It’s impossible for unauthorized people to gain access to the digital key”
Fraunhofer Institute for Secure Information Technology has launched Key2Share, a token-based NFC access control system that enables keys to be shared securely via QR codes.
Keys are issued by the Key2Share server and then sent to a registered user’s smartphone over the air. Once stored on the user’s NFC phone, access rights can be shared with friends, colleagues and employees who are also registered with Key2Share by simply sending a QR code via email, MMS messages or even regular postal mail.
