Claims
- 1. A portable electronic system configured for a secure transaction, comprising:
a card having a width, length, and thickness, wherein a ratio of length to thickness is at least 5; a storage medium to store data; and an integrated circuit device (“IC”) including security information, wherein the storage medium and the IC are provided within the card and; wherein the security information stored in the IC is used to authenticate an access request to the storage medium.
- 2. The portable electronic system of claim 1, further comprising:
a reader to access the storage medium, the reader including a first interface and a second interface, the first interface being configured to interface with the IC and the second interface being configured to interface with the storage medium.
- 3. The portable electronic system of claim 2, wherein the reader further includes:
a security module coupled to the first interface and including a first processor, the security module cooperating with the IC to authenticate the access request.
- 4. The system of claim 3, wherein the security module further includes:
a read-only memory, and a second processor configured to perform encryption or decryption algorithm.
- 5. The system of claim 4, wherein the security module further includes:
a random number generator, and a random access memory.
- 6. The system of claim 1, wherein the storage medium is a non-volatile semiconductor device.
- 7. The system of claim 1, wherein the storage medium is a flash memory.
- 8. The system of claim 7, wherein the IC is provided directly over the flash memory.
- 9. The system of claim 8, wherein an circuit interface is provided between the IC and the flash memory.
- 10. The system of claim 9, wherein the circuit interface is a flexible circuit.
- 11. The system of claim 1, wherein the IC includes a memory, a security information storage area for storing the security information, and a cryptography module.
- 12. The system of claim 11, wherein the security information is a cryptography key.
- 13. The system of claim 12, wherein the memory includes a secured area and a non-secured area.
- 14. The system of claim 1, wherein the storage medium on the card is a disk, the card including a pin that is configured to move along a first direction and a second direction.
- 15. The system of claim 14, wherein the pin moves along the first direction if the card is inserted into a reader to provide an opening for accessing the disk.
- 16. The system of claim 15, wherein the pin moves along the second direction if the card is removed from the reader, thereby closing the opening.
- 17. The system of claim 1, wherein the ratio of the length to thickness is at least 8.
- 18. The system of claim 1, wherein the ratio of the length to thickness is at least about 10.
