Closed door cards generally use encryption to prevent people outside the community from copying the card privately. Normal NFC mobile phones, bracelets and other devices cannot be simulated. Even if the simulation is successful, sometimes the card cannot be swiped normally.

Moreover, the encryption measures of different door cards are different, and the simulation difficulty is further increased. We don’t know how the simulation effect of Redmi Note 10 is, we will wait and see.

Recall the past and present of the Note 10 series NFC 3.0:

NFC 1.0

The earliest NFC analog door card feature, with few application scenarios, can only simulate part of the door card without changing the factory settings. For door cards that have been changed from the factory settings, it may not be possible to swipe the card.

NFC 2.0

It can be accessed to access card service providers, with more usage scenarios, and support for air card issuance (for example: Xiao Ming can in his own community, pass the property reservation mobile phone number authentication, and the card will be successfully opened). The application scenarios have been greatly increased, and the card opening is more convenient. However, limited by the community expansion of access card service providers, it is still unable to meet more needs.

NFC 3.0

With the latest mobile phone NFC door card simulation technology, it covers a wider range of door cards and has a higher credit card success rate. In addition, security has also been upgraded. The second card verification process is introduced for the first time to prevent the card from being swiped by others in the public area to simulate it.
