Is the idea of shoe sticker feasible?
Issue: What if 2 people picked up the shoe at the same time?
I guess the two people will have to fight for the shoe. 
On a more serious note, what are you trying to do?
currently what I’m doing is when sticker detect motion will display information of shoe. It will display information of shoe where sticker is closer to the mobile device. Currently my product is able to work but I have not done the database.
I second to that use case. we also want to implement same use case. Kindly guide through please.
We’re working on adding a demo of this use case as an App Template to Estimote Cloud, next to our existing beacon templates (https://cloud.estimote.com/#/apps/add). Stay tuned!
