Remote mobile payment, or m-payment, is when you use your mobile phone is carry out a transaction for a good or service.  There are a few different ways that remote m-payment can be carried out. One way allows mobile subscribers to buy something through their phone or via SMS, like an application, ringtone, or video, and it billed to their mobile account.  Another way is for mobile phone subscribers to pay directly through a mobile Web site using methods like PayPal, credit or debit cards.

Proximity m-payment is based on contactless near field communications (NFC) and allows consumers to purchase goods and service directly at the point-of-sale using their mobile phone.  Consumers simply hold their mobile phone close to a reader, and the amount purchased is deducted from a pre-paid account, a mobile account, or a bank account.
