I need a Iphone app that reads QR code using iphone camera, decode and proceed the QR code content and relay it to a web server for information checking or data changing.
The procedure goes like this:
1. User A scans a QR code containing a standardized information format
2. User A can bump user B and transfer the code content to user B
3. Both user A and B are then connected via bump connection for transfer for information checking results
During the bump data exchange, a communication channel is set up between user A and user B such that they can transfer data results to each other during an active session. The communication channel involves public key infrastructure, hence it will be good if you know how to deal with RSA public and private key decryption. You can assume that both user A and user B both already have their own RSA keys installed on their iphone app.
Please let me know your previous exposure in RSA decryption such as OpenSSL or otherwise. The rest of the app application should be very simple.
