I'm trying to get my ACR122 (usb) device to emulate a passive NFC tag, but am having difficulty getting the communication to occur properly. I'm hoping someone can see what I'm doing wrong here and help point me in the correct direction. The response on this other question ACR122 - Card Emulation pointed to a document at http://code.google.com/p/nfcip-java/source/browse/trunk/nfcip-java/doc/ACR122_PN53x.txt but when we follow this to the letter it doesn't behave as expected.

How to card emulate with ACR122U-A9

I have a ACR122U-A9, I want to card emulate with it. I ask who has done this point? Can you give me some suggestions? Now I have also other problems, when I put the white smartcard on this NFC reader, LED blinks only once. But when I put the phone on it, the LED always blinks until phone out. The ACR122U contains a PN532 NFC controller chip. The PN532 supports host card emulation through its TgInitAsTarget command (see the PN532 user manual ). In order to pass commands to the PN532, you would connect to the ACR122U just as if it was a normal smartcard reader (e.g. using PC/SC). You can then

Everything work, I can detect the presence of a card but I want to extract the UID/ID of the card. Someone know the function to do that?

I'm

问题 I am trying to develop an Android application for a hospital. In this system there is a need to get the patient information stored in the database in the android phone into the desktop computer using NFC technology. Is there anyway where I could use a NFC USB Reading device (ACR122U NFC Smart Card Reader RFID Writer 5 Mifare USB) to transfer the data from the mobile phone to my desktop computer? The real scenario for this would be, in a hospital when a person wants to take some test results
