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

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.

from the previous NFC support type of card read, the following is to solve the NFC blocking response, if this step is not done, when the system has a number of NFC-enabled applications, will be in the NFC swipe when the number of application options, we need the scene is, The current

Previous "Android" read all the pictures on the SDcard card and show that the reading process has a progress bar display (click the Open link) test on the real machine is very problematic, often encountered memory overflow, the situation of the card dead. Because of the memory on the real machine now, 2G has rarely seen, basically all 8G look like. This app is unfriendly because it puts the read-out image on the a
