METHOD AND SYSTEM FOR CONDUCTING A TRANSACTION USING A PROXIMITY DEVICE |
| 摘要 |
A proximity device (102) transmits a first dynamic authentication value contactlessly to a terminal. The first authentication value is included in a discretionary data field of message data arranged in an ISO Track 1 and/or ISO Track 2 format. Message data is sent from the terminal to an issuer (110). The issuer separately derives a second authentication value and compares it with the first authentication value. |
