Card emulation):This mode is actually equivalent to an IC card using RFID technology.It can replace a large number of IC cards (including credit cards) in shopping malls, bus cards, access control, tickets, tickets, and so on. In this way, there is a great advantage, that is, the card is powered by the RF domain of the non-contact card reader, even if the host device (such as mobile phone) can work without electricity. P2P mode): This mode is similar to the infrared splitter, which can be used

Q: Card simulation on Android NFC mobile phone Modify the last description 1. Q: Can I simulate a card on an androidnfc mobile phone? A: It is technically feasible. However, for general developers, it only seems technically feasible :( 2. Q: How to implement it? A: There are two methods: one is hardware-based, called the virtual card mode (virual card mode), and the other is software-based, it is called host card mode ). In the virtual card mode, y

HCE mode allows the software to simulate smart cards and generate electronic virtual smart cards .HCE (host-based card Emulation) is an analog smart card software that exists as software in Android (for example: APK). HCE is characterized by analog intelligent IC Card (ISO 7816-4), can be used in finance, transportation, communications and other industry applications, HCE is a software simulation of the Intelligent IC card, so there will be aid, can simulate the function of the existing physical

The previous example describes the general steps for detecting and reading and writing NFC tags. This example describes the common Mifare tags. The Mifare Tag can be 1 K, 2 K, and 4 K. The memory partition is similar, and the memory distribution of the 1 K-byte Tag is given: Data is divided into 16 segments, each with 4 blocks. Each Block can store 16 bytes of data. The size is 16X4X16 = 1024 bytes. The last Block in each zone is called A Trailer. It
