Radio-Frequency IDentification (RFID) is the use of a wireless non-contact radio system to transfer data from a tag attached to an object, for the purposes of automatic identification and tracking. Some tags require no battery and are powered by the radio waves used to read them. Others use a local power source. The tag contains electronically stored information which can be read from up to several meters (yards) away. Unlike a bar code, the tag does not need to be within line of sight of the reader and may be embedded in the tracked object.
A new technique for printing RFID chips on paper has been developed by University of Montpellier scientists. The technique uses a thermal evaporation process to deposit thin aluminium coil antennas on sheets of paper, which can later be used for packaging or printed material. The researchers claim this is a cheaper way to produce RFID tags, allowing the technology to replace both barcodes and QR codes.
So am thinking if this technique really works and gets adopted, I can’t imagine the fun things I will like to tag and track. Say where I drop my room keys, where my annoying dog runs to and many other fun thoughts.
