1. You can use HUAWEI Pay's virtual bus card. Open any bus card in Huawei wallet. Next, you only need to set the bus card as the default card, and then go to the company or property card reader to read your mobile phone NFC ID to the access control system, and you can use your mobile phone to swipe the access control card.

2. Use NFC-SIM card (bus mobile phone card). This needs to go to the business hall to handle the relevant card. Of course, the premise of the replacement card is that the mobile phone supports NFC before it can be used. Let's not talk about the cost here. Everyone goes to the business hall for consultation, which is generally very cheap. After you have this card, you need to set it up. In the NFC setting, change the NFC security chip to card 1, and then read the NFC ID of your mobile phone card from the card reader to the access control system, so you can swipe the access control card with your mobile phone.

3. Frequency of access control system: If the access control system is old, it may support 2.4G radio frequency (old radio frequency card, high frequency and ultra-high frequency of radio frequency are not discussed here). The new access control system generally supports 13.56MHz NFC (new IC card), and the mobile phone generally supports 13.56MHz NFC frequency.
