code card for punched cards

The code card goes into the punched card lock and allows punched cards with the same code to access the site.

This code card is indispensable for every code change on your punched cards.

Changing the code card each year blocks old cards that no longer have the right code, so you can check each year who has paid for a new license, for example.

Order with standard or numbered punched cards.

1 code card is required per punch card lock.
