Why did the access card fail to be added?

The access card was added successfully, and the door could not be opened successfully. There may be the following reasons:

1. When adding an access card, only the UID (User Identity Certificate) field of the physical access card is copied. However, the verification mechanism of door locks from different manufacturers is different when swiping cards. Some door locks need to verify other data fields or underlying protocols besides UID when swiping cards.

2. In order to improve the reliability and stability of the access card, the access card of Huawei Mate 20 series mobile phones has been upgraded. The access card of Huawei Mate 20 series mobile phone may have been added successfully, but the card swiping did not respond.

3. The entrance gate is covered by metal or other obstacles.

4. The mobile phone uses a metal mobile phone case or a relatively thick mobile phone case.

5. When the power access gate swipes the card, the induction is weak.

6. If the access card is used normally on other gates, it will only fail to swipe the card on some gates.

The corresponding solutions are as follows:

1. After upgrading the wallet version to the latest version, re-simulate the access card. If the swipe card still fails, it is recommended that you use a physical access card.

2. At present, the access card function only supports some access cards, and more access cards will be added gradually in the future. For the latest news, please pay attention to the official account of Huawei Wallet WeChat.

3. When the entrance guard gate swipes the card, it is necessary to keep no obstacles around.

4. Remove the phone case and try sliding again.

5. Put the NFC sensing area of the mobile phone near the entrance guard to swipe the card, and try to adjust the position and angle of the NFC sensing area and the entrance guard when swiping the card.

6. It may be that there is a compatibility problem between the access card reader and the mobile phone, and the special physical card (elevator card/meal card/water drop card) does not support simulation. Successful simulation will also lead to card swiping failure. At present, there is no unified standard for access control system in China, and there are many protocol processes. Huawei wallet access card may not support the protocol process of access card reader. In this case, it is recommended that you use a physical access card to swipe your card.

In addition to the above solutions, you can also try:

1. Please upgrade the Huawei wallet version to the latest version (Huawei wallet >; My > check for updates).

2. Delete the access card, add it again and try to swipe it.

3. Restart the phone, restart the NFC switch, and try to swipe the card after switching the default card. (setting method: click wallet > my > credit card settings > default card, just select the card you want to set, Huawei wallet 9.0. 17.300 and above: enter Huawei wallet > my > settings > default card settings. )

4. Confirm whether it is an access card that simulates a smart door lock (such as highland barley and Anpu Hotel). When adding an access card for a smart door lock, only the UID (User Identity Certificate) field of the physical access card is copied. However, the verification mechanism of door locks of different manufacturers is different when swiping cards. Some door locks need to verify other data fields or underlying protocols besides UID when swiping the card, which makes it impossible to open the door. Huawei Wallet doesn't support this card for the time being. I suggest you use a physical access card for the time being.

5. When simulating the access card, you will be prompted that "all contents cannot be read, only the card number is copied at present" or "all contents cannot be read, only part of the information of the card is copied". Please upgrade your wallet to the latest version, upgrade your system to the latest version of the current network, and try to simulate the access card again. If it still fails, it is because the encrypted card contains card number information and encrypted content. Due to the differences in the verification mechanism of door locks of different manufacturers when swiping cards, some door locks need to verify other contents except the card number information when swiping cards, which will lead to the failure to open the door. Huawei wallet does not support this card for the time being. It is suggested that you temporarily use physical access cards or create blank cards to write cards in the property.
