What is RFID tags?
• It’s a wireless tracking system that consists of tags and readers.
• Radio waves are used to communicate information/identity of objects or people to nearby readers – devices that can be hand-held or built into fixed positions like poles or buildings.
• The tags can carry encrypted information, serial numbers and short descriptions.
• There are also high-memory tags like the ones designed for use in the aviation industry.

Types of RFID tags:
• Active RFID tags
• Passive RFID tags

Active RFID tags
• Active RFIDs use their own power source, mostly batteries.
• Active tags can ping information every few seconds like beacons, or they can get activated when a reader is in the proximity.
• Active tags have a longer read range, around 300 ft, compared to passive tags.

Passive RFID tags
• Passive RFIDs, on the other hand, are activated through the reader using the electromagnetic energy it transmits.
• This is enough power for the tag to transmit information back to the reader.
