The Facepay application uses smart contracts on the Ethereum blockchain. These smart contracts encompass all guest, merchant, and payment information. There is no longer any reason for the chaos at your cash register.
Merchants use Facepay to manage accounts for your guests. Your guests don't need to download or do anything.
All accounts are securely stored in the distributed ledger.
Checkout is the worst part of any guest visit. Facepay eliminates it, and returns control of the customer experience to you, the merchant.
