   MST is designed to transmit from within 3 in (76 mm) of the magnetic card reader. [3] Outside of physical transmission, there are no changes to the magnetic stripe card system (i.e., reception, processing, information content, and cryptographic protocols). However, the information being transmitted being dynamic may allow tokenization.
