1, the ID number recognized by NFC is only queried by the pseudo-real-name registration system. Only the physical card number of the ID card is read, and the number is converted into computer text in the form of OCR photography, and the ID number is displayed on the mobile phone, which will have a certain error rate.
2. It is impossible to read the personal information of the ID card, but to read the information of the ID card, you need an encryption module certified by the Ministry of Public Security, and you can decrypt it with an algorithm.
3.NFC is a big specification. At present, the existing protocol documents support three protocols: 14443A/B, 15693 and Felica. The ID card belongs to the type of 14443B, so from the link layer, ID card reading is supported.
4. The ID card is a smart card, and the upper communication should be based on 78 16 protocol. There are access restrictions in the 78 16 protocol. Trying to access the content of the ID card involves a series of authentication processes, and it is impossible to access the content without the corresponding key.
Extended data:
Near Field Communication (NFC), also known as near field communication, is a short-distance high-frequency wireless communication technology, which allows contactless point-to-point data transmission and data exchange between electronic devices. This technology evolved from the contactless radio frequency identification (RFID) jointly developed by Philips and Sony, and is based on RFID and internet technology.
Near-field communication is a short-range high-frequency radio technology, which works in the range of 20 cm, the frequency is 13.56 MHz, and the transmission speed is 106 kbit/s, 2 12 kbit/s or 424 kbit/s. ..
Near field communication service combines near field communication technology and mobile communication technology, and realizes many functions such as electronic payment, identity authentication, ticketing, data exchange, anti-counterfeiting and advertising. This is a new service in the field of mobile communication. Near-field communication service has changed the way users use mobile phones, made users' consumption behavior gradually electronic, and established a new consumer and business model.
The application of (NFC) technology has been widely concerned around the world, and different roles such as telecom operators and mobile phone manufacturers at home and abroad have carried out application pilots one after another, and some international associations have also actively promoted standardization. According to the prediction of relevant institutions in the industry, the mobile phone application based on near field communication technology will become the next killer application of mobile value-added services.
The main features of near-field communication technology are: wireless communication technology for short-distance (within 10cm) safe communication; The RF frequency is13.56 MHz; ; Radio frequency compatibility is ISO 14443, ISO 15693 and Felica standards; The data transmission speed is 106kbit/s, 2 12 kbit/s and 424kbit/s. ..
