Why does the Xiaomi 15 take longer to load the NFC card interface on first use?

This is normal behavior. When using the NFC card for the first time, the device needs to access the network to load the NFC card data. NFC (Near Field Communication) is a wireless technology that allows devices to communicate with each other by simply being in close proximity. It is widely used for contactless payments, ticketing, and data exchange between devices. The first time you enter the NFC card interface, the device can take a moment to retrieve and load the necessary data. After this initial process, the system will remember the information, and subsequent uses will be much faster without additional loading time. This feature ensures a smooth and efficient experience when using NFC-enabled services.
