AN IDENTIFIER TOKEN WITH ELECTRONIC CIRCUITRY AND CONDUCTOR MEANS IN THE TOKEN EXTERNAL TO THE CIRCUITRY FOR REALIZING AN IDENTIFIER CODE |
摘要 |
An identifier token has an electronic circuit with a bidirectional electronic interface for accessing the circuit. The circuit comprises an identifier code. The code is realized by bonding the circuit to a conductor external to the circuit as part of a non-volatile coding mechanism. The code may be stored in an on-board EEPROM that is fixated by bonding its write enable pin to an appropriate voltage. A second realization is by means of selective coding interconnections between a series of bond pads and a conductor for forming a string of code elements.
