A method of transmitting authorisation data, said authorisation data for authorising a process. The method comprises securely providing an encryption key to an encrypter and a decrypter; encrypting at the encrypter input authorisation data with the encryption key; converting the encrypted data into an optical code pattern; displaying the optical code pattern on a display device; reading the optical code pattern with an optical reader; converting the optical code pattern into received encrypted data corresponding the encrypted data; decrypting the received encrypted data at the decrypter to generate decrypted data corresponding to the input authorisation data, and authorising the process with the data corresponding to the input authorisation data. |
