What is RFID Technology?
Radio-frequency Identification (RFID) uses radio waves to transmit a unique ID between an asset that is tagged and a reader at a range that can reach up to 180 feet.
RFID tags come in a variety of forms and material types such as plastic, rubber, and metal. They can be attached via glues, cable ties, or even rivets. By default, RFID tags are powered by incoming radio signals from the reader at distances from 3 to 15 feet, meaning they do not require any power. Without a battery that loses power over time, these passive tags can last virtually forever.
For applications that require longer range, battery assisted tags can be used to signal up to 180 feet. Sometimes called “active” tags, the batteries in these can last for years. Even when they die, the tag can continue to work in a passive mode at a shorter range.
There are 2 types of RFID readers:
Readers are typically small and portable handheld devices or gateways that create a passthrough that allows for numerous items to be scanned at the same time. RFID can be used to automate asset tracking in and out of a location. This makes RFID ideal for assets on the move. RFID can be used with almost any piece of equipment.
