What is the distance for 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 do you measure RFID frequency?
It is difficult to detect, from just looking at the tag, whether it is operating at 124 KHz or 134 KHz. If the manufacturer’s name or a model number is printed on the tag, you will probably be able to search the Internet to find its specifications.
How much are active RFID tags?
Generally speaking, active tags are $25 and up. Active tags with special protective housing, extra-long battery life or sensors can run $100 or more. A passive 96-bit EPC inlay (chip and antenna mounted on a substrate) costs from 7 to 15 U.S. cents.
What is the minimum read distance for RFID tags?
Minimum read distance of over 1 meter or 3 feet. Gen2 tags can have a read range of over 16 meters or 52 feet when using the full 4 Watt EIRP legally allowed on the readers by FCC and other global regulators (For your local power regulations see our RFID Education page).
How does the read angle affect the range of an RFID?
The two are separated by some Z distance, and they never touch. In short, you’ll get the best range when you read the tag face-on – the steeper the read angle, the more the read range will decrease. Some RFID tags, such as the embeddable RFID wire tag, have a 360 degree read profile which mitigate the read angle concern.
How can I increase the read range of my RFID reader?
Higher power settings will result in greater read range, while lower power settings will result in decreased read range. Also, in order to maximize read range, ensure that your reader is set to its highest receive sensitivity. The details: All RFID readers have the ability to control how much power they send through the cables to the antennas.
How much transmit power do I need for RFID?
The higher the transmit power the greater is the RFID range. But you can’t just use as much power as you want, to achieve the range you require, or you could interfere with radio receivers that aren’t even part of your RFID system. This could be serious if they were part of a critical medical application. Therefore…
