How Does it Work?

By embedding keywords into text messages sent to specific numbers, cell phones can transmit commands that tell the wireless provider to add a given amount of money to the user's bill. When the bill is paid, the phone company transfers the amount designated to the recipient. Some carriers may charge a fee for sending the text message according to the user's existing phone plan. Traditional banks allow access to accounts through mobile applications without using the wireless carrier as an intermediary.
