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). MST technology is accepted at nearly all payment terminals with a card reader. Some payment terminals may require software updates. Simply select a card from Samsung Pay, and transmit the payment information by moving your device within an inch of the payment terminal. Your transaction and payment information will be kept private and secure with the use of tokenization. MST is more secure than using a traditional payment card and is as secure as paying with Near Field Communication (NFC).
When calls or texts are exchanged between two numbers of same service provider it is called on net call.
On the other hand, call/text exchange between two numbers of different service providers is called off net call.
Example: Airtel to Airtel transaction will be called on net.
Airtel to Vodafone will be off net.
