Barrier-free channel usage precautions

Barrier-free channel usage precautions

1. The card and the hand, metal or other distracting objects are put together through the barrier-free passage, the card cannot be identified, and the reading rate is too low.

2. If the card is not standardized, if the card is parallel to the ground, the reading rate is too low.

3. After the same card passes through the barrier-free channel, it will take 3 seconds to pass the barrier-free channel again, otherwise the card will not be recognized.

4. After learning to tie the card and untie the card in the background, the synchronization delay time is a variable parameter, the default is 10 minutes, and takes effect after 10 minutes.

5. Multiple cards overlap and pass together, and the card cannot be recognized.

6. Multiple cards do not overlap, and they are opened and passed together, and only one card number is randomly read.

7. The barrier-free channel only supports ID cards. Our company previously introduced IC cards, so the school needs to re-apply for cards. The newly-entered schools recommend the use of composite cards (including IC and ID card numbers).
