Check hardware version
lsusb shows the device:
Bus 003 Device 004: ID 072f:2200 Advanced Card Systems, Ltd
lsusb -v shows also the firmware version bcdDevice:
idVendor 0x072f Advanced Card Systems, Ltd idProduct 0x2200 bcdDevice 1.00
The Version this howto is about is the above ACS ACR122U PICC firmware 1.0.
First install this:
# pacman -S pcsclite pcsc-tools pcsc-perl ccid
Optionnal : install pcsclite-libudev
Versions prior to pcsclite 1.7.2-2 were compiled with udev disabled and used libusb; if you need such old version you can use the pcsclite-libudev package from AUR. Otherwise, please go on to the next section.
# cd /tmp # wget https://aur.archlinux.org/packages/pcsclite-libudev/pcsclite-libudev.tar.gz # tar -xf pcsclite-libudev.tar.gz # cd pcsclite-libudev # makepkg # sudo pacman -U pcsclite-libudev-*.pkg.tar.xz
Install the ACS CCID PC/SC driver
Install the acsccid package from AUR:
# cd /tmp # wget https://aur.archlinux.org/packages/acsccid/acsccid.tar.gz # tar -xf acsccid.tar.gz # cd acsccid # makepkg # sudo pacman -U acsccid-*.pkg.tar.xz
With old versions of the ACS driver, you can get errors like these:
ifdhandler.c: In functie ‘IFDHControl’: ifdhandler.c:1304:8: fout: ‘PIN_PROPERTIES_STRUCTURE’ has no member named ‘wLcdMaxCharacters’ ifdhandler.c:1305:8: fout: ‘PIN_PROPERTIES_STRUCTURE’ has no member named ‘wLcdMaxLines’
In such a case, you can try commenting out those to lines in src/ifdhandler.c.
Put a tag on the reader and try to scan your Touchatag:
# /etc/rc.d/pcscd start # pcsc_scan
You should get something like this:

If you encounter a problem like this:
# pcscd -f ccid_usb.c:859:ccid_check_firmware() Firmware (1.00) is bogus! Upgrade the reader firmware or get a new reader. ifdhandler.c:104:IFDHCreateChannelByName() failed readerfactory.c:1050:RFInitializeReader() Open Port 200000 Failed (usb:072f/2200:libusb:006) readerfactory.c:233:RFAddReader() ACS ACR122U PICC Interface init failed.
The libnfc README suggests to do this:
If your Touchatag or ACR122 device fails being detected by PCSC-lite daemon (pcsc_scan doesn't see anything) then try removing the bogus firmware detection of libccid: edit libccid_Info.plist configuration file (usually /etc/libccid_Info.plist) and locate "<key>ifdDriverOptions</key>", turn "<string>0x0000</string>" value into 0x0004 to allow bogus devices and restart pcscd daemon. Warning: if you use ACS CCID drivers (acsccid), configuration file is located in something like: /usr/lib/pcsc/drivers/ifd-acsccid.bundle/Contents/Info.plist
tagEventor runs in the background and executes scripts when a tag enters or leaves your tag reader.
Run tagEventor to test your installation:
# tagEventor -v 1
The scripts are located in /etc/gtagEventor. Read the tagEventor documentation on how to use them.
The following AUR packages might also be worth a try:
