We have been selling Bitcoin locally and are working on a store kiosk. Any thoughts of how to implement this device?
What do you mean by kiosk? Are you refering to a bitcoin ATM? In that case, there are companies out there that deliver ready-made units. A quick google turned up this one:
https://lamassu.is/I think what OP is referring to is something that look like a booth with tables and chairs and a live person attending to queries from Bitcoin buyers and transaction will be done manually by an attendant. Not a bad idea but instead of saving money from paying a small space and electricity for the Bitcoin ATM, for kiosk type will eat more space and needs manpower plus electricity.
