The chip is intended for use in passive UHF transponder applications. IC derives its operating power from an RF electromagnetic field generated by a reader, which is received and rectified by the chip ...

[pc486] sent in his hack that uses an ATtiny85 to act like an EM4102, a chip used for RFID tags. Minimally, all that is needed is the AVR and a coil, but he recommends some filtering capacitors.

Each tag’s sensor material and coil antenna provide data related to how the RF interrogation is received. The researchers aim to offer a more sustainable alternative to standard UHF RFID technology ...

RFID tags are great little pieces of technology, but unfortunately, the combination of paper, metal, and silicon means they are as bad as some modern pregnancy tests — single-use electronic ...

This device uses a board with an RFID IC to store power from the reader's ... the thermometer and write the result to the dynamic RFID tag. The tag is then read by the reader (most likely a ...

Internet-of-Things (IoT) technology provider Impinj Inc. (NASDAQ: PI) is riding a strong secular tailwind as the world ...

Warehouse operations, retail outlets, and many other industries are leveraging IoT solutions using RFID tags and wearable devices. We'll look at the leading technologies and discuss how they may ...

"The power and area reductions in Synopsys' ULP NVM IP enable us to maintain our strong position as a turn-key solution provider in the UHF RFID tag IC market," said Murilo Pessatti, CEO at Chipus.

For RFID applications such as toll collection and vehicle and container tracking, the tags are used over and over for many years. Such tags are built into a plastic housing like handheld ...
