Therefore, the invention forms the fingerprint identification smart card with the battery double interfaces.
The present embodiment is different from the above-described embodiments in that the secondary battery 28 of the transaction processing unit 2 of the present embodiment is charged by the dual interface chip 27. When the card is used, the card body 1 is inserted into the reading device, the dual-interface chip 27 is electrically contacted with the reading device, and then the reading device supplies power through the dual-interface chip 27, so as to generate required power to the dual-interface chip 27 of the transaction processing unit 2, and the power management module 23 stores part of the power to the secondary battery 28. In addition, the card body 1 is close to a reading device, the antenna 25 is used for reading electromagnetic waves from the reading device, so that the required electric power is induced and generated to the dual-interface chip 27 of the transaction processing unit 2, and the power management module 23 is used for storing partial electric power to the secondary battery 28. The reading device is further enabled to supply power to the transaction processing unit 2, the switch unit 3 and the fingerprint identification unit 4 through the dual-interface chip 27, so as to perform the contact transaction or the non-contact transaction as mentioned in the third embodiment. The power in the secondary battery 28 may be used as a backup power, and may be used for supplying power when the dual interface chip 27 cannot obtain the power of the reader. Therefore, the invention can better meet the requirement of practical use.
In summary, the fingerprint identification smart card provided in the embodiments of the present invention can obtain external power from the transaction processing unit during use, and the fingerprint identification unit receives and identifies the fingerprint data of the card holder, so that the switch unit can turn on the transaction processing unit to perform a transaction with the reading device according to the identification result of the fingerprint data, or turn off the transaction processing unit to perform no transaction, thereby achieving the purpose of improving the security and convenience during the transaction.
