| 摘要 |
A transponder-initiated transaction system is electromagnetically coupled to an account transponder device at the point of sale. The account transponder device may be embedded within a watch, key chain or other personal article for convenience or affinity. The transponder device may communicate account information to an RF-enabled point of sale device, enabling transactions to take place without resort to remote data processing facilities. In other embodiments partial or complete account information may be accessed or stored at co-located or remote sources. New account registrants may access a Web site to enter a transponder ID and activate a new account, which may be a credit account, debit account, cash account, special purpose vending account, or other types of accounts. |
