  2. Review • Future Register • Utilizes customer input to facilitate transactions in a low inventory fast food setting. • Can communicate with a customer’s NFC-enabled cell phone to digitally transmit credit card information and receipts • Vendor will be able to customize the inventory through the user interface.

  3.
