Method 1:APDU command ffca000000 read uidAcr122u APDU command> 04 76 BF E1 BF 02 80 90 00 Method 2: Because the UID of the Mifare ultralight card is in the first page and second page of the card, we can directly read You can retrieve one page 2 data. Acr122u read page > 04 76 BF 45 90 00 > Data read at start page 00 > Number of bytes read: 04 > Hex mode: 04 76 BF 45 Acr122u read page > E1 BF 02 80 90 00 > Data read at start page 01 > Number of bytes read: 04 > Hex mode: E1 BF 0

Android, BlackBerry all provide the analog NFC card API, theoretically can use the phone to simulate a meal card, traffic card, and even bank card to carry out identity authentication, trading, is not very happy, the mood is very excited ah. Wait The reality is Application Scenarios: Most of the domestic, 99% of the cards are the cheapest M1 cards, and the entire system only applies the card UID data. The UID of an

Type 1 Tag,type 2 tag, Type 3 tag, type 4 Tag Type 1 is based on ISO 14443 A and are currently available exclusively from Innovision Technology (topaz™). It has a 96-byte memory capacity, which makes it a very cost-efficient tag for a wide range of

This article describes in detail how to migrate the NFC Reader library to the Kinetis k64f microcontroller. This article uses a real-world porting case to demonstrate the steps required to migrate the NFC Reader library to the sample target MCU. The purpose of this article is to serve as a guide for software developers

If you think NFC can only be used in Google Wallet or MasterCard paypass, it is wrong, because NFC can be used far more than that. With the increase in the number of NFC mobile phones, NFC tags have become a common method to use this emerging technology. However, many Android users still do not know how to use these

According to foreign media reports, RIM's joint chief executive Jim Balsillie recently launched the BlackBerry Tag service at the GITEX conference in Dubai. With this service, users can share their contact information, files, and multimedia content by touching their mobile phones. RIM revealed that the BlackBerry Tag service will be integrated into BlackBerry 7 software updates based on

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 d

RFID Tags: (citation) RFID Radio Frequency identification is a non-contact Automatic identification technology, which automatically identify the target object by radio frequency signal and obtain relevant data, identification work without manual intervention, can work in a variety of harsh environments. RFID technology can identify high-speed moving objects and can identify multiple electronic tags at the same time, fast and convenient operation.Card reader
