environmental effects on rfid tag antennas We have studied the effects of nearby objects on the read range of several types of RFID tags, and the impedance, pattern, and radiative efficiency of antennas that closely emulate the tag structures, using measurements and simulations. The WAVE ID Plus Papercut Reader is a dual-frequency card reader for identification and .NFC tags and readers communicate wirelessly with each other over very short distances. Tags store a small amount of data on them that is sent to the reader in the form of electromagnetic pulses .

We have studied the effects of nearby objects on the read range of several types of RFID tags, and the impedance, pattern, and radiative efficiency of antennas that closely emulate the tag structures, using measurements and simulations.
Emerging new tags (new antenna materials and miniaturization) and readers (antenna miniaturization) hold the potential to reduce 25–70 % and 3–10 % for most of the environmental impact categories, respectively in comparison with currently applied technologies. Four environmental applications of radiofrequency identification tags are discussed: (1) reduction of traffic congestions through RFID-enabled congestion pricing; (2) rewards for recycling. We have demonstrated the possibility to obtain functional UHF RFID passive tags by screen-printing antennas using a semi-transparent, non-metallic, and environmentally friendly conductive paste. Antenna film thickness could be controlled by consecutive overlay printing (~1.24 µm/layer), with direct impact on the optical transmittance, sheet .
RFID antennas relies on etching of metal layers deposited onto thin lms, which is a complex and environmentally unfriendly processing method [2, 4, 6]. An auspicious alternative for low-cost and large-scale production of UHF-RFID tags is based on printing techniques such as screen-printing, gravure-printing, exography, and inkjet-printingIn this paper, we present environmentally friendly UHF RFID tag antennas that are manufactured by inkjet printing silver nanoparticle ink on a plain paper substrate after finding the most efficient manufacturing parameters and the optimal number of printed layers.
