ELECTRONIC CIRCUIT CHIP FOR AN RFID TAG WITH A READ-ONLY-ONCE FUNCTIONALITY |
| 摘要 |
It is described an electronic circuit chip for an RFID tag. The electronic circuit chip comprises (a) an access circuit configured for coupling the electronic circuit chip to an antenna element of the RFID tag, and (b) a memory device being connected to the access circuit. The memory device is configured for storing a secret value, for making retrievable the secret value, and for deleting the secret value. Deleting the secret value is accomplished if the secret value has been retrieved by means of a first attempt procedure for retrieving the stored secret value. It is further described an RFID tag comprising such an electronic circuit chip and a method for managing the use of a read-only-once secret value by an RFID tag with such an electronic circuit chip. |
