Touchatag is a RFID Reader

About Touchatag

Touchatag is a RFID tag reader from Touchatag. It is a cheap set consisting of an ACR122U USB tag reader and MiFare Ultralight RFID tags.

It is available here or for Europe here.

Remember: Always put a tag on the reader, otherwise you might encounter problems!

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.

Install Touchatag

First install this:

# pacman -S pcsclite pcsc-tools pcsc-perl ccid

Optional : 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.

Test Touchatag

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

Install tagEventor

tagEventor runs in the background and executes scripts when a tag enters or leaves your tag reader.

Download a binary version or compile your own.

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:
