M1 time card, speed, security, storage capacity upgrade again

With the development of the smart card industry, radio frequency card technology is also becoming more and more mature, peoples demand for card entry and exit, 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 with you, the card can be placed in your pocket or bag at will, and you can enter and exit the gate freely.

The M1 card is divided into the S50 and S70, the S70 being an upgraded version of the S50. Lets take a look at the parameters of the S50 and S70 in comparison.
