Electronic security system comprises programmable data storage means (18) and program storage means (16), both associated with data processing means (12), typically in an integrated circuit microprocessor (10). One user-related accessing means (22A) has storage for machine-readable data individual to its intended user. Access means (20) serves to read said data individual to intended user, so that, at a first reading thereof, at least some of that data is written to said programmable storage means (18), which data will be used at subsequent readings of the accessing means (22A) to deny access to and/or some sought operation of the data processing means (12) except for the one user-related accessing means (or a copy thereof). The one accessing means (22A) can be written to at point of sale. Another type of accessing means (22B) can be used prior to the one accessing means and/or in prescribed association therewith either to store and transfer other data to the programmable data storage means (18) or to re-write said data individual to intended user. |
