ID4us - no chip inside

Chipless RFID tags significantly extend read range and tag localization accuracy, while reducing the reader’s power consumption and the per-tag-costs down to 1 cent.

Moreover, chipless RFID tags enable full tag flatness and full printability.

However, beside such distinct advantages with a breakthrough potential in various markets, Chipless Tags impose demanding challenges, like maximizing the number of stored and detectable bits as a function of the available tag surface and the required reading range. Solving such challenges depends on the requirement of the specific application.

The vision of ID4us is to replace the widespread barcode with chipless RFID tags by means of novel Digital Signal Processing, Artificial Intelligence and Technological Advances in Printable Nano Electronics.

Application Fields


Cheap Tag – What if the price per tag would reach 1ct?

If the price per tag could reach 1 ct, then truly cheap products can finally be tagged under economic aspects. Or to put it in more simple terms, all "paper-based products" could be enriched with a Chipless Tag.

Locate Tag – What if a tag could be localized with centimeter accuracy?

If a tag could be localized with centimeter accuracy, then it would be possible for the contents of boxes to be correctly assigned to each box from remote distance. Cameras for the localization and identification of objects would no longer be needed for securing privacy, and humans, machines, and robots would have a better awareness of where things are.

Far Tag – What if the reading range of a tag could reach 100 meters?

If a tag could be read in a range of 100 meters then fast moving vehicles could be made aware of crossing obstacles earlier. Cost-consuming localization and identification infrastructure could be saved, and the penetration through objects would be significantly improved, which also means having a larger read range in severe so-called 'non-line-of-sight' scenarios.

Thin Tag – What if a tag could be thin and flat?

If a tag could be as thin as a strand of hair and flat then it could be invisible below a coating or paint layer (even on metal). It could be robust against movements due to the absence of bonding between chip and antenna and it could simply be seamlessly embedded in all paper-based products.

Printed Tag – What if a tag could be printed and/or bent?

If a tag could be printed and/or bent, then it could be laminated on curved objects (also on metal). It could be individualized for flexible materials and it could simply be seamlessly embedded in all paper-based products.
