I use my Opal card with my Samsung phone case and it works great. Mine does. It doesn't work on the iPhone 6 because of the Apple Pay functionality. While it is not available in Australia, the chip seems to still be active. I have a windows phone with NFC and place it at the opposite .NFC on-card key-gen. Roughly every third key generation on card fails with all .
This article walks through the basics and advanced principles related to how UHF RFID Passive tags communicate via backscatter. Before reading, it is important to know about the types of coupling and when each one is used. If you do not know what coupling is and how it works, please refer to " Principles of . See more

This article walks through the basics and advanced principles related to how UHF RFID Passive tags communicate via backscatter. Before reading, it is important to know about the types of coupling and when each one is used.We derive a theoretical formula for RCS of an RFID tag with a minimum scattering antenna and describe an experimental measurement technique which involves using a network analyzer connected to an anechoic chamber with and without the tag. This video will show you how RFID systems work in industrial applications to track transport equipment. RFID readers on rail lines and in shipping yards/ports keep track of container movements.
This paper proposes an optimal 4 Quadrature Amplitude Modulation (4QAM) backscatter scheme at 920 MHz, which can increase the throughput and simultaneously improve energy utilization. In this optimal scheme, the reflection coefficient modulus | Γ | .The accuracy of time-of-flight based ranging systems is fundamentally limited by the available bandwidth. This paper first analyzes the UHF RFID backscatter channel formed by convolution of the individual constituent channels.
Passive and semipassive UHF RF identification (RFID) systems have traditionally been designed using scalar-valued differential radar cross section (DRCS) methods to model the backscattered signal from the tag.

Abstract—Passive and semi-passive UHF RFID systems have traditionally been designed using scalar-valued differential radar cross section (DRCS) methods to model the backscattered signal from. This article presents the design and implementation of a passive, computational ultra high frequency (UHF) radio frequency identification (RFID) platform using vector backscatter modulation on the uplink (tag-to-reader). Backscatter radio has been extensively used in commercial radiofrequency identification (RFID) applications in sub-gigahertz bands to wirelessly transmit static identification codes with.
UHF RFID backscatter channels is fundamentally limited by the available bandwidth and highly dependent on the channel characteristics. Comprehensive wideband channel measurements are presented and analyzed with respect to parameters which influence the potential ranging performance.
