FUNDAMENTALS OF COMPUTER

Detailed explanation-1: -Radio frequency identity (RFID) chips are tiny computer chips connected to miniature antennas that can be placed on or in physical objects. They are used in a wide variety of applications where “contactless” authentication is desired, including toll booths, transit passes, passports, and contactless entry keys.

Detailed explanation-2: -RFID tags are a type of tracking system that uses radio frequency to search, identify, track, and communicate with items and people. Essentially, RFID tags are smart labels that can store a range of information from serial numbers, to a short description, and even pages of data.

Detailed explanation-3: -Often the term “RFID” is loosely used to describe both, but there’s a big difference between them: RF tags all send the same, simple signal and simply tell the receiver that something is present; RFID tags send more complex signals that uniquely identify whatever they’re attached to.

Detailed explanation-4: -A radio frequency identification reader (RFID reader) is a device used to gather information from an RFID tag, which is used to track individual objects. Radio waves are used to transfer data from the tag to a reader. RFID is a technology similar in theory to bar codes.
