So What is Chipless?

RFID systems involving codes/symbology that do not contain a silicon chip Potential to produce the lowest cost RFID tag Capabilities for printing directly on top of products or packaging Passive/ Read onlyFrequencies above UHF


Tens of Millions= Secure access, test tubes/blood samples, toys

Hundreds of millions= Laundry, library, livestock, logistics, assets security

Billions = Pallets, cases, air baggage, smart paper tickets, banknotes, financial cards, parcels drugs, archiving

Trillions= Supermarket barcodes, brand protection

Yearly Market PotentialSource: IDTechEXToday, no more than several hundred million RFID devices

are sold yearly.

InkSure Vision for Chipless RFID

Achieve a sub-cent cost target for fully printed tag

Provide a completely printed symbology on or within the product/package using digital or conventional printing technologies with focus on inkjet engines.

Provide an anti-counterfeiting solution based on the unique RF properties of the ink used for printing the tag.

Address the reading of printed labels in difficult real life conditions

Non-line of sight

Any orientation/angle

Anti collision effect-identify single tags within tag groups

Provide 25bit to 96bit information applications


How our Technology Works

The existence of diffraction has limited the extent to which symbols or images (such as barcodes) can be compressed.

Diffraction is the bending, spreading and interference of waves when they pass by an obstruction or through a gap. When a bar code symbol is placed too near another symbol, its waves interfere with those of its neighbour (diffraction) and vice versa, making it impossible to accurately read either bar.

This limitation has restricted the density with which symbol based codes can be printed, and therefore the minimum size required for machine-readable codes. By extension, this has also limited the number of digits which can be used, for example, in barcodes.


Technology: Diffraction Phenomena

Current technologies do not take into account that the diffraction phenomena are predictable. That is, it is possible to place 2D objects within extremely high density, yet still use deductive methods to identify them

Although the labels produced using this method are 2-dimensional, the phenomena itself produces a 3D effect. In this way, it is possible to derive the exact position of the label, even if behind an obstacle. This capability minimizes the challenge of correctly identifying objects that are located directly behind other objects (“collision”)


Technology: Using The Diffraction Phenomena

Our approach : devise a code of simple objects together with algorithms for interpreting the phenomena produced when they are printed close to each other

Depending upon the wavelength used to query and transmit the information and the code used, it is possible to print the desired level of information in small areas

• No silicon chip required

• 96-bit printed code consumes only 10% of the conductive ink required for a printed RFID antenna

Detection principles based on Synthetic Aperture Radar (SAR), Interferometer Synthetic Aperture Radar (ISAR) and RF Holography (RFH)


Each code produces a unique image.Red colors indicate the presence of code informationImage processing algorithms detect the image and extract its information

Segmentation of label information from backgroundMultiple image separationFurther analysis of the image completed only in the labels area



96 Bit Tag Structure - Concept

• Sequence of 37 symbols, each positioned (or not) in 1 of 9 potential vertical positions

• Special symbols for tag positioning

• 96 bits matrix = EPC code capacity

• Very high error correction capacity

• Tag dimensions = 108mm x 15mm

108mm x 15mm
