A Stamp Code allows customers to collect stamps on your Stamp Card. It can be used multiple times and it does not expire.
That being said, you should put your Stamp Code somewhere safe where staff can supervise stamp collections to ensure members do not take more stamps than they should. You may also want to consider setting up a time delay between stamping.
The most convenient place to locate your Stamp Code for both customer and staff is usually by the point of sale (POS). Alternatively, some people keep it behind the cash register and present it upon a qualifying purchase.
We recommend you either frame or laminate your Stamp Code to keep it clean.
