NFC tags are passive, meaning they don't have any power source. Instead, they literally draw power from the device that reads them, thanks to .

Chipless RFID tags are RFID tags that do not require a microchip in the transponder. RFIDs offer longer range and ability to be automated, unlike barcodes that require a human operator for interrogation. The main challenge to their adoption is the cost of RFIDs. The design and fabrication of ASICs needed . See moreTo understand the development of chipless RFID tags, it is important to view it in comparison to classic RFID and barcode. . See moreMany improvements have been done in the past few years on communication systems, based on electronic devices where an integrated circuit is at the heart of the whole system. . See moreLike various existing RFID technologies, chipless RFID tags are associated with a specific RF reader, which questions the tag and recovers the information contained in it. The operating .

Thus, in chipless-RFID tags, the tag is equipped with a planar encoder (typically .The low-cost mass fabrication of these flexible-electronic printed products, such as RF .

These tags can collaborate with high-throughput printing processes such as .Chipless RFID tags are RFID tags that do not require a microchip in the transponder. RFIDs offer longer range and ability to be automated, unlike barcodes that require a human operator for interrogation. Thus, in chipless-RFID tags, the tag is equipped with a planar encoder (typically a printed pattern containing the ID code) and sometimes with an antenna for communication with the reader. By using low-cost conductive inks, the price of the tag can be substantially reduced.

The low-cost mass fabrication of these flexible-electronic printed products, such as RF identification (RFID) tags, wireless sensors, conductive tags and readers, touchpads for keyboards, and display applications, all require knowledge of additive production techniques and appropriate substrates. These tags can collaborate with high-throughput printing processes such as inkjet printing and gravure printing to considerably bring down the cost of a single tag. Chipless tags can be categorized into two classes: time-domain or frequency-based RFID tags.

The printed radio-frequency identification (RFID) of a sensory tag is chipless with the fully printable feature, Nonline-of-Sight (NLoS) reading, low cost, and robustness to the environment. The detection and adoption of security features for such tags in .This paper presents a fully-printed chipless radio frequency identification sensor tag for short-range item identification and humidity monitoring applications. The tag consists of two planar inductor-capacitor resonators operating wirelessly through inductive coupling. Printed chipless RFID tags have attracted attention due to their high-volume yet low-cost manufacturing flexibility. Chipless RFID tags are sometimes referred to as 'planar transmission line resonators' and can be printed on flexible plastic and paper substrates.

Two types of chipless tags, one based on time-domain reflections and the other based on frequency domain signatures, are introduced. To enable a fully printed encoding circuit, linearly tapering technique is adopted in the first type of tags to cope with parasitic resistances of printed conductors. The flexibility to use low-cost printing techniques makes chipless RFID a competitive technology. In this paper, we report an evaluation of the microwave performance of two different screen-printed chipless tags in the 3–6 GHz range. A time-domain, chipless-RFID system with 80-bit tags inkjet-printed on ordinary DIN A4 paper, which can be easily programmed and erased, so that identical tags can be fabricated on a large scale (and programmed at a later .
