S-Pay - How MST works ?
Magnetic Secure Transmission (MST) is a technology that emits a magnetic signal that mimics the magnetic strip on a traditional payment card. MST sends a magnetic signal from your device to the payment terminal's card reader (to emulate swiping a physical card without having to upgrade the terminal’s software or hardware).
