How to open the access card for Xiaomi 8?
Step 1: Open a blank card on Xiaomi's mobile phone, open the door card page of Xiaomi's wallet, click "Add Virtual Door Card", select "Custom Blank Card" and agree to the relevant agreement, then click "Open Card Now". Conduct identity authentication, and the simulation can be successful after the authentication is completed. Step 2: Open the access card offline. After the virtual door card is successfully added, it will be offline (residential property, school or other offline scenes). In fact, this is Xiaomi's own "door card simulation" function, which can be completed by opening Xiaomi wallet.
Step one:
Open the Xiaomi wallet in the mobile phone and slide to find the "key card"
(Some versions are displayed as "Door Card Simulation")
Step two:
Click to enter the "Door Card" interface, and it is suggested to select "Simulated Physical Door Card" (generally you already have a physical door card).
Step 3:
Select "Start Detection" and put your key card at the NFC antenna. It is best not to touch it, as shown in the figure.
Generally speaking, the door card simulation can be realized by completing the above three steps.
If you find that your simulation has failed, there are generally several reasons.
1, encrypted key card, not supported.
2. Only door cards with frequency of 13.56MHZ are supported.
3. Door card simulation does not support bank cards and bus cards.
4. Support NFC but don't display it (it is recommended to update the system)
5. Some users need to get Root permission before simulation.
Generally, the above reasons may lead to the failure of your key card simulation. After checking the above reasons, it is still impossible to simulate. You can use other professional software, or you can handle it manually at the residential property office.
