TAG
is an art work created during
the
Art Hack
Day in Stockholm (April 2013).
Download
and use the TAG Android app to draw and create. Then write
your work to an SL Access card. Use the TAG app again to read
and view the image stored on a card. Shake the phone to clear
the screen.
The image is stored on, what seems to be, some unused storage
space on the SL Access cards. There are no guarantees in life,
but test have shown that some of the tagged cards continue to work as
usual in the public transport system.
To use the app, you have to allow unsigned apps and enable NFC
on your device.
