There are 2 kinds of tags that work with the touchatag service:

RFID tags and 2D barcode tags

RFID tags can be read by a touchatag USB RFID reader and by certain models of mobile phones.
2D barcodes can be read by any mobile phone with a camera - as long as you have reader software installed

In case you don't have either of these, you can still resort to our UID input box that will let you manually insert a Unique IDentifier (UID)
