I use an app that timestamps the date, time, and location on the photo. I've had to use it for other shops requiring photos of the front of stores. I'm noticing that more and more MSC want a timestamped photo of the location on top of business cards/receipts. Off the top of my head I can think of 3 companies that have required me to take a time stamped photo as proof.
Just a guess but they want to make sure people are actually doing the shops you knowing spending enough time with the associate and getting the recommendation. A photo before and after shows this.As far as the phone in the store they have two different versions I have seen one where they prefer it but its not mandatory the other where its a required photo. Easy to get it while waiting to be assisted or after being assisted.
Well does any have a shop in a Radio Shack store anymore? They all ways tell you not to do a shop in a Radio Shack. I thought they went out of business a few years ago. I get a kick out of young Sheldon being so enamored with Radio Shack.
