linux usb nfc reader Since Linux kernel version 3.1, a few kernel-modules must not be loaded in order to use libnfc : "nfc", "pn533" and "pn533_usb". To prevent kernel from loading automatically these modules, you can blacklist them in a modprobe conf file. Near Field Communication (NFC) technology operates on the principles of magnetic field induction and radio frequency . See more

Most commercial devices (also called NFC Reader) are physically attached through USB and either provide a native USB interface or a virtual serial port. The nfc.ContactlessFrontend manages all communication with a local device. In general I would recommend a device based on the PN532 chip as they are natively supported by Linux's nfc-tools and the libnfc on which the tools are based: http://nfc-tools.org/index.php/ACR122. If you want to use USB to connect to your reader / writer, I would go for the ACR122U. Apparently there's something special about the ACR122U that causes the Linux NFC driver to conflict with the CCID (Chip/Smart Card Interfaces) driver. As a workaround, you can unload the NFC kernel module associated with the NFC chip on that device (PN533): I need to read some NFC cards by a USB reader on a Linaro/Debian OS. The USB reader has a HID profile. Presenting a 13,56 MHz card the keyboard returns a code. I read about a command to send to the device but, since it is a (virtual) keyboard, I cannot send commands, and toward which device? How to dump the memory of the card? Thanks

Looking for an NFC card reader working on Linux. Hi! For my goverment smart ID card I would need a NFC Smart Card reader, as it only support communication via that. I have two questions regarding this: Is any USB NFC reader a good choice, or .I installed PyUSB and I'm able to detect the device using some of the sample code, but nothing like reading the NFC card when it comes into proximity (although there is a beeping sound, which makes me believe the USB device itself is working fine).Since Linux kernel version 3.1, a few kernel-modules must not be loaded in order to use libnfc : "nfc", "pn533" and "pn533_usb".
