Marking Standing Trees with RFID Tags

Smart RFID Tags

RFID has been identified as one of the cornerstones of the upcoming Internet of Things (IoT) and the focus is moving from conventional RFID towards next generation pervasive networked and interconnected systems. In the future IoT billions of objects are envisioned to report their identity, location, environmental conditions and history over wireless connections. An on-going effort that will sup...

Agents on RFID tags

Antennas of RFID Tags

Radio Frequency Identification (RFID) is a rapidly developing technology which uses RF signals for automatic identification of objects. RFID system generally consists of three components: 1) A small electronic data carrying device called a transponder or tag that is attached to the item to be identified, 2) A reader that communicates with the tag using radio frequency signals, 3) A host data pr...

Chipless Rfid Tags

a compact multi resonator circuit for Chipless rfid tag is presented in this paper. The basic resonator is a shorted λ/4 Stepped Impedance Resonator (SIR). The tag is designed and simulated using High Frequency Structure Simulator and a 6 bit prototype is fabricated on rtduroid(εr=2.2 and tanδ=.0008) Substrate in area of 4.5x2cm2. Data is coded as amplitude variations in the frequency domain. H...

TANGO: Supporting Vocabulary Learning with RFID tags

This paper describes a computer-assisted language learning (CALL) in a ubiquitous computing environment. The environment, called TANGO (Tag Added learNinG Objects) system, detects the objects around the learner using RFID (Radio Frequency Identification) tags, and provides the learner the right information for language learning. This system supports learning in daily life with PDA (personal dig...
