I know Square has ignored this feature request for years. Let me describe why it's critically important, and should be included, at least at the Loyalty level:
I have a coffee shop in an area where many other shops exist. There are some businesses around whose employees essentially keep us afloat. For these businesses, we promote a discount to keep their staff coming back, and need to be able to give the employees a reliable way to redeem.
These "loyal" customers will usually come in and mention their workplace to have the barista apply the discount, but they are often not comfortable doing that over and over, as different baristas are working or if the same barista doesn't remember them. When they don't get the discount on their second visit because we didn't remember their workplace, they often give up on ever getting the discount, thus never become "loyal" customers.
If these customers have a code they use, then there's no question, they can use it at their will without ever being uncomfortable about things.
THIS IS A REAL ISSUE. EITHER ADMIT THE FEATURE'S NOT ON THE LIST OR IMPLEMENT IT, PLEASE.
Thanks,
JD
