CrossID researches "printable" RFID tags

February 19, 2004

Israeli startup CrossID promises "printable" RFID tags using some chemicals' magnetic properties: the particles resonate when subject to electromagnetic waves from a reader. Each chemical emits its own distinct radio frequency, or "note," that is picked up by the reader, and all the notes emitted by a specific mix of different chemicals are then interpreted.

If implementable, this technology could be used from protecting sensitive documents (think military secrets) to bank-note tracking; copy protection (if all the copiers in a building have a detector built in and the exits of the building has detectors) and more.

"printable" RFID tags ????

They have been already existing !!!!

If I am not mistaken, Motorola produces special resonant RF readers for detection of specific chemicals mixed with ink, glue or paper bulk. These chemicals were invented and procuced by Micro-Tag.

I saw in field applications of this perfect technolochy to tax stamps, credit cards and brand labels and was really admired. Indeed, it is really strange moment, that RFID News passed by that technology and haven't even mentioned it writing on CrossID.

How is it possible for either CrossID or Inkode (uses short embedded metal fibres of different lengths and resonant frequencies) or Micro-tag to produce a consistently readable and 96bit EPC compliant "unique" serial number ?
- are they really going to individually detect 96 different chemicals or frequencies ?

Just how toxic are these chemicals ?

How hard wearing and stable are they during transport ?

These technologies might be used for "watermarking" or even the equivalent of a manufactuerer product code, akin to existing Electronic Article Surveillance anti-theft tags but surely they are not suitable for RFID tag style individual item serial numbers ?

The CrossID and Inkode technologies also seem to require 10Ghz to 66Ghz readers i.e. well into the Passive Millimetre Wave Radar Camera (which can "see under your clothes") and military satellite communications range.
