How RFID Works

RFID, or radio frequency identification, uses different frequencies of radio waves to communicate its information. Almost like listening to a radio station. A typical RFID system consists of readers, antennas, handhelds, and tags. These systems can either be active or passive. Active RFID means that the tags are battery-assisted and periodically transmit information like a beacon. Passive RFID is powered by the radio waves that are blasted from the reader or handheld, allowing the tag information to be read.

RFID does not need line of sight

For a barcode to read the information properly you need to be right over the tag. Radio-frequency identification, however, does not require a direct line of sight between the label or tag and the reader. RFID readers and handhelds blast radio waves that interact with RFID tags to record and exchange data. Depending on the hardware that is used the read rage can vary from 10cm to 100m.

Tags can store more data

The standard barcode is limited to the amount of information or data it can represent. An RFID chips memory can hold anywhere from 96 bits to 8 kilobytes of memory.

Read rate is increased

Each barcode needs to be scanned individually to be processed into a system. As for RFID, you can read multiple tags at the same time. RFID readers are capable of processing hundreds of tags at the same time.

A barcode can be printed with the RFID tag

If you already have a barcoding system in place and would like to bring RFID in phases, Printable RFID tags and labels do allow barcodes to be printed on the tags for data collection.
