Here’s an open source RFID cloner design that is about the same size as a standard RFID key card. It doesn’t need a battery to capture key codes, just the magnetic field generated by an RFID ...

which can stealthily snag the information off an RFID card at long range. If you’ve worked with passive RFID before, you know that most readers only work within inches of the card. In [Fran’s ...

Data is power. According to Dinesh Bharadia, an associate professor at UC San Diego in the Department of Electrical and ...

UC San Diego researchers have developed scalable, low-cost passive sensors that work without batteries using RFID technology.

The Naval Autonomous Data Collection System (NADACS) will introduce new RFID technology, as well as improving passive RFID, for Naval Supply Systems Command.

This project leverages conductive yarns, knitting technology and the use of a passive radio frequency identification (RFID) tag. The aim was to create of a wearable wireless telemetry device that ...

This approach bypasses traditional power needs, making sensors more accessible and sustainable, this development could ...

The RFID tags that are routinely inserted into shipping boxes are passive RFID tags, which comprise an antenna, a small integrated circuit, and about 2 kilobits (2K) of memory on a chip with no ...

RFID tags contain, at minimum, two components: an antenna to collect and radiate an RF signal and an integrated circuit which stores and processes the tag identity, modulates the corresponding RF ...

For other applications, passive RFID tags can be read up to approximately 10 feet away, while active tags with batteries can be several hundred feet from the reader. Linear polarized antennas ...
