Mobile money transfer (MMT) allows users to transfer money from one person to another through their mobile phones. It provides an instant, convenient and secure way to transfer funds. To use MMT, a user needs a bank account linked to their mobile number. They can then send funds to another user by entering their 10-digit phone number and 7-digit account identifier. In India, MMT is currently bank-led and requires registration with a participating bank. Major banks like HDFC, SBI and Axis have partnered with telecom companies like Vodafone, Airtel and Idea to offer mobile money services in India.
