If you are a high-value target, such as an employee with an access card to valuable or sensitive assets, then using an RFID-blocking sleeve or wallet is sensible. So, an RFID blocking wallet is worth it for that peace of mind that .
The power transfer coefficient (PTC) accounts the capability of the tag in transferring the power which is obtained from the reader to the RFID microchip and is given as follows: where \({Z}_{in}=\mathrm{Rin }+\mathrm{ j Xin}\) and \({\mathrm{Z}}_{\mathrm{chip}}=\mathrm{Rchip }+\mathrm{ j . See moreThe performance of the tag designed here is also analyzed by plotting its radiation characteristics, i.e., efficiency and gain in Figs. 8 and 9, respectively. . See more

The antenna covers two UHF bands allocated for RFID use in Europe (866-868 MHz) and N. America (902-928 MHz) with a dual-band PIFA element as well as HF 13.56 MHz band with a near-field coil.
UHF multi-antenna RFID readers provide powerful solutions for applications requiring broad, simultaneous coverage of multiple zones. Equipped with multiple antennas, these readers can monitor large areas, making them ideal for high-volume asset tracking and complex environments.
In this paper, a broadband UHF RFID tag is proposed. By introducing a coupling loop and four bent dipoles, two resonant modes are excited in UHF RFID band, which results in a total 194 MHz (806MHZ-1GHz) 3dB operational bandwidth. It covers the entire UHF band (860 MHz-960MHz). Frequency-ranges used for RFID-systems. As shown in Fig. 4, several frequency bands have been assigned to RFID applications: 125/134 KHz, 13.56 MHz, 860-960 MHz, 2.450 (2.400–2.483) GHz and 5.800 (5.725–5.875) GHz. Several issues are involved in choosing a frequency of operation (Dobkin 2007). This study proposes a new, low-cost tri-band rectenna operating in UHF RFID, GSM-1800 and UMTS-2100 frequency bands. The waves operating in these three frequencies bands come from RFID applications and access networks of telephone operators deployed in the human environment.

Dual-frequency RFID tags combine the benefits of two different frequency ranges. For example, a tag could use HF for access control purposes and UHF for inventory management purposes. This allows for more efficient and accurate tracking and management of assets and inventory. In this work, an RFID tag antenna with dual-band operation, i.e., operating in North American and European RFID bands is designed. The designed tag antenna possesses high radiation efficiency and high realized gain in both the resonating bands.
