Product Introduction:

Early access cards were mostly ID cards without storage function, but later developed into logic encryption cards with storage and encryption functionsLater on, larger storage space and higher key strength were usedThe CPU cardWith the continuous development of smart card technology, people have become increasingly concerned about door restrictionsThe security requirements for cards are also increasing. As a result, higher security access control (identity recognition) cards have emerged. Our company producesThe HD-S5-GM CountryThe card reader for the secret door adopts a data encryption algorithm that supports higher security strength provided by the National Cryptography Administration（SM1）ofFM1910 non-contact CPU card reader chip.
The HD-S5-GM national security door card reader meets the practical requirements of high stability, high security, easy maintenance, and convenient expansion in the circuit design of the access control system. It uses solid-state capacitors and tantalum capacitors, industrial grade chips, switch type DC buck power supply, and a complete RS485 protection circuit.
