Abstract

The present invention discloses a RFID access apparatus and a Transaction method using the same. The RFID access apparatus, coupled to a SD card socket disposed in an electrical terminal device including a controller unit coupled to said SD card socket and a radio frequency transceiver coupled to said controller unit, and being capable of accessing data recorded in a RFID tag through operating said electrical terminal device, comprising: a SD interface, coupled to said SD card socket for signal and data communication; a radio frequency access unit, coupled to said SD interface for reading data recorded in said RFID tag and writing data into said RFID tag; and a memory unit, coupled to said SD interface for storing data. By using the RFID access apparatus, a transaction method can be performed in the following steps: providing an electrical terminal device comprising a SD card socket; inserting a RFID access apparatus, comprising a memory unit recording an electric currency, into said SD card socket; accessing a price, stored in a RFID tag attached on a product, by operating said electrical terminal device; and making transaction.

Claims

1. A RFID access apparatus, coupled to a SD card socket disposed in an electrical terminal device including a controller unit coupled to said SD card socket and a radio frequency transceiver coupled to said controller unit, and being capable of accessing data recorded in a RFID tag through operating said electrical terminal device, comprising:

a SD interface, coupled to said SD card socket for signal and data communication;

a radio frequency access unit, coupled to said SD interface for reading data recorded in said RFID tag and writing data into said RFID tag; and

a memory unit, coupled to said SD interface for storing data.

2. The RFID access apparatus according to claim 1, wherein said radio frequency access unit is capable of reading and writing said RFID tag through radio frequency emitted from said radio frequency transceiver.

3. The RFID access apparatus according to claim 1, further comprises an radio frequency transceiver coupled to said SD interface for transmitting and receiving ultra high frequency signals to access said RFID tag.

4. The RFID access apparatus according to claim 1, wherein said electrical terminal device is a mobile phone.

5. The RFID access apparatus according to claim 1, wherein said electrical terminal device is a personal assistant device.

6. The RFID access apparatus according to claim 1, wherein data stored in said memory unit further comprises an electric currency.

7. A transaction method using RFID access apparatus, being capable of purchasing a product having a RFID tag, comprising the steps of:

(a) providing an electrical terminal device comprising a SD card socket;

(b) inserting a RFID access apparatus, comprising a memory unit recording an electric currency, into said SD card socket;

(c) accessing a price, stored in a RFID tag attached on a product, by operating said electrical terminal device; and

(d) making transaction.

8. The method according to claim 7, wherein said step (d) further comprises the steps of:

(d1) if said electric currency is larger than said price then deducting the amount of said price from said electric currency; and

(d2) displaying successful trading message and the residual of said electric currency on said electrical terminal device.

9. The method according to claim 8, wherein said memory unit further stores a private information of user.

10. The method according to claim 9, wherein said step (d2) further comprises a step of writing said private information in said RFID tag through operating said electrical terminal device.

11. The method according to claim 7, wherein said step (d) further comprises the steps of:

(d3) if said electric currency is smaller than said price then stopping transaction; and

(d4) displaying erroneous trading message on said electrical terminal device.

12. The method according to claim 7, wherein said RFID access apparatus further comprises a radio frequency transceiver.

13. The method according to claim 12, wherein said radio frequency transceiver is operated in bandwidth of ultra high frequency.

14. The method according to claim 7, wherein said electrical terminal device is a mobile phone.

15. The method according to claim 7, wherein said electrical terminal device is a personal assistant device.
