摘要
A dynamic code of a transaction device may be validated by a remote processor by comparing the dynamic code to a verification code generated using a timestamp and identification data received from the transaction device. A static code may replace the dynamic code for authorization processing. A remote verification processor may synchronize to the transaction device using the timestamp. A token may be associated to each communication interface of a multi-card transaction device. A display may be directly connected to driver circuit on a display board of a transaction card. A radio IC chip may be included in a powered card. A multi-card device may toggle a plurality of display screens to display transaction data.
