A mobile payment is a payment made using a mobile device such as a smartphone or tablet. Mobile payments can be made in-person, online, or in-app. In-person mobile payments can be made using NFC-enabled devices at NFC-enabled point-of-sale terminals. Online and in-app mobile payments are made using a mobile device and a mobile payment processor.
Some of the emerging trends in mobile payments include the use of near field communication (NFC) technology, the use of QR codes, and the use of biometrics.
