If there's "no point in faking it", why does the page make a big deal about uniqueness and ? In your scenario, a GPS fix serves equally well.

The claim "Like snowflakes, no two SnowShoe Stamps are exactly alike." is wrong. If you stamp my phone, your SnowShow Stamp will have the same exact signature as a carefully carved potato.

in my view: 1-because it is key for each store to have a unique stamp 2- I don' think so,what about stores in the same building or stores very near each other? 3-no two officially produced "snowshoes" though, anyway yes no one would keep you from 3d printing the stamp of another store so that you can have your customers pay that store instead of yours, but I don't see any clear advantage in it, and, as i said before, the app would probably show you the store name before proceeding
