Why can’t I use the access control card set up on my Huawei mobile phone?

If the access control card is added successfully but the door cannot be opened successfully, there may be the following reasons:

1. When adding the access control card, only the UID (user identity certificate, i.e. unique identification) of the physical access control card will be copied. field, but door locks from various manufacturers have different verification mechanisms when swiping the card. In addition to verifying the UID, some door locks also need to verify other data fields or underlying protocols when swiping the card. Please upgrade the wallet version to the latest version and simulate the access card again. If the card swiping still fails, it is recommended that you use a physical access card.

2. The access control gate is covered by metal or other obstacles. When swiping the card, the access control gate needs to be kept clear of obstacles around it.

3. If your mobile phone has a metal phone case or a relatively thick phone case, please remove the phone case and try swiping the card again.

4. The induction of the powered access control gate is relatively weak when swiping the card. Please put the NFC sensing area of ??the mobile phone close to the access control gate to swipe the card. When swiping the card, try to adjust the position and angle of the NFC sensing area of ??the mobile phone and the access control gate.

5. The access control card works normally on other gates, but fails to be swiped on some gates. Since special physical cards (elevator cards/meal cards/water drop-shaped cards and other special-shaped cards) do not support simulation, some access control cards may fail to swipe if they are successfully simulated. This situation may be due to compatibility issues between the access control card swiping machine and the mobile phone. Currently, there is no unified standard for domestic access control systems, and there are multiple protocol processes. Huawei Wallet Access Control Card may not support the protocol process of the access control card swiping machine. If you encounter this situation , 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 gt; My gt; Check for updates).

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

3. Restart the phone, restart the NFC switch, enter Huawei Wallet One-click Repair, switch the default card and try to swipe the card. The method of switching the default card is as follows:

Setting method: click Wallet gt; My gt; Swipe Card Settings gt; Default Card, select the card you want to set.

Huawei Wallet version 9.0.17.300 and above: Enter Huawei Wallet gt; My gt; Settings gt; Default Card settings.

Huawei wallet version 9.0.17.300 or below: Click Wallet gt; My gt; Card settings gt; Default card, select the card you want to set.

Warm reminder:

If the default card of Huawei Wallet is set to "Smart Flash Card", the default card will be automatically closed, but the default card function does not support cancellation.

The cards that can be set as the default card are: Huawei Pay bank card, Huawei Pay transportation card, eID, access control card, smart home door lock, and hotel room card.

The default card to bring up the card swiping interface relies on the NFC function. If the device does not support NFC, setting the default card is not supported at the moment.

If the default card has been set in advance, after confirming that NFC is turned on, bring the camera on the back of the phone close to the card swiping machine (no need to light up the screen), and the phone will automatically pop up the card swiping interface (if the default card is set to a bank card) , need to verify the lock screen password), you can swipe the card.

4. Confirm whether you are simulating the access card of a smart door lock (such as Qingbai, Anpu Hotel). When adding the access control card of the smart door lock, only the UID (User Identity Certificate, i.e. unique identification) field of the physical access control card is copied. However, there are differences in the verification mechanisms of the door locks of various manufacturers when the card is swiped, and some door locks are not calibrated when the card is swiped. In addition to verifying the UID, other data fields or underlying protocols need to be verified, resulting in the failure to open the door. Huawei Wallet does not currently support this type of card. It is recommended that you use physical access cards for the time being.

5. When simulating an access card, it prompts "Unable to read all content, currently only copying the card number" or ""Unable to read all content, only copying part of the card information"", please upgrade your wallet to For the latest version, upgrade the system to the latest version of the current network and try to simulate the access card again; you can use a mobile phone that supports the super access card function to add it. For mate 40 and X2 series mobile phones, please upgrade to HarmonyOS 3.0 before adding it again. Super access card is not supported. Functional mobile phones can use the super access card sharing function to share and then add. In addition to verifying the card number information, other contents need to be verified, which will result in the door being unable to open. Huawei Wallet does not currently support this type of card. It is recommended that you temporarily use a physical access card or create a blank card to write the card at the property.
