The first passive transponders powered by incoming RF date back to the early 1970s, as does the vision for most of today’s manifold RFID applications. Yet only with advances in semiconductor ...

In the previous article, “The principles of RFID: Active Tags,” we discussed a classification of RFID tag called the active tag. Even though the active tag has many applications, it does not get as ...

Now that most smartphones are equipped with Near Field Communication technology, RFID providers are offering a wide variety of NFC transponders. “We’ve certainly seen a lot of changes in the industry” ...

In technical terms, inductive coupling is the transfer of energy from one circuit to another by virtue of the mutual inductance between the circuits. In an RFID system that uses inductive coupling, ...

NFC, or near field communication, is a popular wireless technology that allows you to transfer data between two devices that are in close proximity to each other. It’s often used as a faster and more ...

A few months ago Hackaday covered the xNT crowdfunding campaign which aimed at making an NTAG216 based NFC implant for different purposes. I actually backed it, found that standard NFC readers don’t ...

Applications of radio-frequency identification (RFID) are widespread in today's well-connected society. Found in nearly every market including government, transportation, food, health care, retail, ...

The FCC approval NPI103479 certifies a "Construction Toy with Bluetooth Transceiver" operating in the 2402–2480 MHz range – classic Bluetooth Low Energy (BLE) in the 2.4 GHz ISM band. According to ...
