Title: How to use NFC to swipe access control
With the rapid development of science and technology, NFC (Near Field Communication) technology has been widely used in various fields of daily life, among which access control systems are one of the most common applications. This article will introduce in detail how to use NFC to swipe access control, and provide hot topics and hot content in the past 10 days as a reference.
1. Basic principles of NFC access control
NFC is a short-range wireless communication technology that allows devices to exchange data within a few centimeters. In access control systems, NFC is usually used for identity verification. Users only need to bring an NFC-enabled device (such as a mobile phone or card) close to the card reader to complete the door opening operation.
| Device type | Support NFC function | Applicable scenarios |
|---|---|---|
| Smartphone | Most Android and some Apple phones | Personal use, temporary authorization |
| NFC card | Special access card | Long-term use, enterprise access control |
| smart watch | Some high-end models | Portable use |
2. How to use mobile phone NFC to swipe access control
The following are the detailed steps for using mobile phone NFC to swipe access control:
1.Check if your phone supports NFC: Enter the phone settings and check if there is an NFC switch in the "Connections" or "Wireless & Networks" options.
2.Turn on NFC function: Turn on the NFC switch in settings and ensure that the phone can be recognized by the card reader.
3.Add access card: Some mobile phones support the simulated access card function, and access card information can be added in "Wallet" or "NFC Settings".
