Abstract
A near field communication (NFC) based checkout system comprises an NFC enabled mobile telephone that reads product data from an NFC tag associated with a product. The mobile telephone updates a shopping list when the consumer scans an item. The consumer uploads the shopping list at a payment terminal at the checkout via an NFC link. The payment terminal connects with a price look up (PLU) database and downloads the price data for the items in the shopping list to provide a total price. The payment terminal requests authorization of the total price from the consumer'"'"'s financial authorization.
