Hello richelle87, it must be simple if we wish to see crypto payments in the real world, since unfortunately today there is no efficient solution for paying for groceries, food, drinks, services directly with cryptocurrency, the goal of Eterbank is to make buying coffee, pizza etc with crypto simple, once it is achieved more innovative features will be added, not before.
It's really nice to hear about the intentions of your project here in bitcoin community. It will be a good kind of investments in the future but I have doubts on this, because I did not read or here any news about a specific grocery store that accepts crytocurrency. Is it really possible to happen?
The Unique Value Proposition for businesses is a means to enable users to spend their cryptocurrency (with EterWallet) with said business (Though a simple app, EterPOS), while dealing a business only in FIAT (no crypto fluctuation, exchange / regulatory problems for the business).
EterPOS will be free, with no monthly fees only transaction fees and therefore bringing businesses only added value in case there be demand for crypto payments, therefore any grocery store will have the possibility to download EterPOS, sign up and create a business account and start charging cryptocurrency users and getting paid in FIAT from Eterbank.
