What RFID Frequency Is Right For Me?
RFID cards and key tags come in three frequencies. The main differences have to do with the reading distance between the reader and the card or key tag.
LOW FREQUENCY
Low Frequency (LF) – 125 kHz
Also known as: Prox, HID, Clamshell
Read range: 1”-2”
HIGH FREQUENCY
High Frequency (HF) – 13.56 MHz
Also known as: MiFare, i-Class, NFC
Read range: 2”– 5”
ULTRA HIGH FREQUENCY
Ultra High Frequency (UHF) – 900 MHz
Read range: 2” to 30’
When looking for cards you should start with the specification of the reader that the cards or key tags will work with. If you have the flexibility to choose a reader then you can select the card and reader frequency that is right for your environment.
If your current application supports checking-in people with a member ID number then you can use RFID today. Each RFID card or key tag has a unique number. When that individual scans their RFID card or key tag to an RFID reader, your application will instantly recognize the unique number and person assigned to it.
