6.6.5 Recommended method for access rights management (using prog. cards)
In case of managing access rights of plenty of users (using programming cards only), it is
appropriate to establish a table, which summarizes operation with the reader module
memory. All operations (adding and deleting cards) should be stored in the table. Following
example shows correct usage of the programming cards and proper filing of the actions:
Inserting 5 new cards using the procedure from chapter 6.6.1 – Read + (inserting)
programming card, read cards 1-5, after 15 s the programming mode is exited,
create a table.

programming card. Register the change in your table.
