1 Incorrect sensing position of membership card: When using the sensing lock, you need to put the membership card in the correct position to ensure that there is enough distance between the card and the card reader and the card is stable, otherwise the system will not be able to read the card information and automatically eject the card slot.

2. Fault of inductive lock: The inductive lock system is faulty, such as card reader, slot spring, slot, etc., and the bayonet cannot be ejected normally.

3. Authentication failure: In some cases, although the membership card was successfully sensed on the card reader, the system failed to authenticate the membership card, membership package and usage rights according to the membership card information, resulting in the card slot not being ejected.
