Dynamic Receipts with API Calls

[maprules1000]

There's already ways to customize receipts, but would it be reasonable/possible to dynamically customize receipts based on what customers purchase? I'd like to be able to sell enhanced wifi access at a coffee shop. I'd have my api listen to the Square Connect API for the sale, provision a new user/password or just access code, and then hand that back to square to print on the receipt.

I sat at a register and ran a simple test in a coffee shop and found that customers buy enhanced wifi access much more frequently at a register than on their device after making a purchase.

Would anyone have any different ideas on how to sell wifi access & automatically provision it through the Square Register?

It would be hard to inject information like that into the reciept dynamicly, but you could pre generate a bunch of passwords and update the item after each sale with a fresh password. There are a couple other people doing similar things, like using some of the reciept information as a wifi password, etc.
