Title:
【発明の名称】電子回路を有する識別名トークン及び識別名コードを実現するための回路に対する外部のトークンにおける導体手段
Document Type and Number:
Japanese Patent JPH10511488
Kind Code:
A
Abstract:
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.
