ABSTRACT:
A secured metal token using a single wire communication system is employed to dispense units of value and to provide a secure storage device for controlling the dispensing of articles or service items. The metal token can be formed of two pieces with a simplified electronic circuit inside which can contain units of value for the dispensing of items using the memory within the metal token as a secure vault. The token uses a simple two wire (ground and combined clock/data) arrangment. As goods are purchased or services rendered the value of those good or services is deducted from a prestored amount within the token.
