ABSTRACT:
A system and method for distribution of articles or services, especially adapted to be secure against use by unauthorized personel, receives first and second data carriers. Each data carrier includes a processor, data storage, and interfacing circuits. A random number generator feeds a random number to each of the data carriers which use a program to generate a resultant based on the random number, a secret code and an identification number. The secret code and identification number are stored in the data storage of each data carrier. The resultants are compared to determine if they are equal, in which case access is allowed.
