With the development of the smart card industry, radio frequency card technology is also becoming more and more mature, peoples demand for access to the card, from the original need to pull out the card from the pocket to sense the development of the current era of automatic induction without pulling out the card. As long as you carry a long-distance induction card, the card placed in the pocket, bag, you can freely enter and exit the gate.

M1 card is divided into S50 and S70, and S70 is the upgraded version of S50. Lets learn about the parameters of S50 and S70 in the following comparison.
