What is the read range of RFID?
Generally speaking RFID tag maximum read distances are as follows: 125 kHz. and 134.3 kHz. Low Frequency (LF) Passive RFID Tags -read distance of 30 cm (1 foot) or less – usually 10 cm (4 inches) unless you are using a very large tag which can have a read distance of up to 2 meters when attached to metal.
How can I improve my RFID reader range?
How to Improve RFID Read Range
- Antennas. Higher-gain antennas get more power from RFID readers compared to lower-gain antennas.
- Polarization. Polarization talks about the type of electromagnetic field the antenna produces.
- SOAP Method. SOAP stands for size, orientation, angle and placement.
- Reader Settings.
- Shorter Cables.
What is RFID and how does RFID work?
RFID stands for Radio Frequency Identification. An RFID device serves the same purpose as a barcode or a magnetic strip on the back of a credit card. It uses radio frequency waves to wirelessly transfer data between itself and a RFID label or a tag attached to an object in order to identify,…
How does a RFID asset tracking system work?
In its simplest form, RFID asset tracking is a way of automating the management and locating process of physical assets. It works by loading an RFID tag with data and attaching it to a relevant asset. This data can include anything from name, condition, amount, and location.
How does RFID tag work?
An RFID tag works by transmitting and receiving information via an antenna and a microchip — also sometimes called an integrated circuit or IC . The microchip on an RFID reader is written with whatever information the user wants.
How do RFID readers work?
At a basic level, each tag works in the same way: Data stored within an RFID tag’s microchip waits to be read. The tag’s antenna receives electromagnetic energy from an RFID reader’s antenna. Using power from its internal battery or power harvested from the reader’s electromagnetic field, the tag sends radio waves back to the reader.
