RFID Frequency

There are four different frequency ranges used for tags: low, high, and ultra-high and microwave?

RFID technology uses radio waves to communicate and therefore different radio frequencies effect that communication. The most common frequencies used are low (125 KHz to 135 KHz), high (13.56 MHz), ultra high (850MHz to 956MHz), and microwave (2.4 GHz). Different frequencies offer comparative advantages in range, power, and cost and are therefore used with consideration of the required application.

How do I know which frequency is right for my application?

As stated above, different frequencies offer comparative advantages in range and power and are therefore used with consideration of the required application as well as other business considerations such as cost effectiveness.

Low Frequency tags have short ranges, but are also less expensive and use less power making them ideally suited for mass production such as security access cards and tracking assets.

High Frequency and Ultra High Frequency tags provide longer reading ranges and high speed data transfer, but have a higher system cost.
