Card-key / Key


Card-key is made of stainless steel; because The Card-key works like traditional mechanical lock, it does not need to use extra electricity. When people put the card into the slot, inserting in the card could drive the gear to unlock the door. In the same way, when people need to go out they push the card into the slot from indoor, and get the card from outside, this is a good way to decrease the trouble things that people forgot to bring key. Moreover, Card-key is more beautiful and easier for carry than traditional key.
