Radio Fre­quen­cy Iden­ti­fi­ca­tion (RFID) tech­nol­o­gy oper­ates across a vari­ety of fre­quen­cy ranges, which sig­nif­i­cant­ly impacts the per­for­mance, read range, and appli­ca­tions of RFID tags. Under­stand­ing these fre­quen­cy ranges is cru­cial for select­ing the right RFID solu­tion for your spe­cif­ic needs. RFID tags oper­ate in three main fre­quen­cy cat­e­gories: Low Fre­quen­cy (LF), High Fre­quen­cy (HF), and Ultra High Fre­quen­cy (UHF).

Below is a detailed overview of each fre­quen­cy range:

Low Frequency (LF) RFID

Fre­quen­cy range: Typ­i­cal­ly oper­ates between 125 kHz and 134 kHz.
Read­ing range: The read­ing range is usu­al­ly short, with a max­i­mum of 10 cen­time­ters (4 inch­es).
Fea­tures: Low-fre­quen­cy RFID tags are less sen­si­tive to inter­fer­ence from mate­ri­als such as water and met­al, mak­ing them suit­able for appli­ca­tions such as ani­mal track­ing, access con­trol, and vehi­cle iden­ti­fi­ca­tion.
Appli­ca­tion Cas­es: Com­mon­ly used in live­stock track­ing, key­less entry sys­tems, and some indus­tri­al appli­ca­tions.

High Frequency (HF) RFID

Fre­quen­cy range: Oper­at­ing fre­quen­cy is 13.56 MHz.
Read­ing range: The typ­i­cal read­ing range is approx­i­mate­ly 10 cen­time­ters to 1 meter (3.3 feet).
Fea­tures: High-fre­quen­cy RFID tags sup­port high­er data trans­mis­sion rates and are com­mon­ly used in appli­ca­tions requir­ing short-range com­mu­ni­ca­tion. They are also com­pat­i­ble with NFC (Near Field Com­mu­ni­ca­tion) tech­nol­o­gy.
Appli­ca­tion Cas­es: Wide­ly used in con­tact­less pay­ment sys­tems, library book track­ing, smart cards, and tick­et­ing sys­tems.

Ultra-High Frequency (UHF) RFID

Fre­quen­cy range: Oper­at­ing fre­quen­cy is between 300 MHz and 3 GHz, with the most com­mon range being 860 MHz to 960 MHz.
Read­ing range: A read­ing range of sev­er­al meters is pos­si­ble, typ­i­cal­ly up to 12 meters (39 feet) or more, depend­ing on the tag and read­er.
Fea­tures: UHF RFID tags have a faster read­ing speed and can read mul­ti­ple tags simul­ta­ne­ous­ly, mak­ing them ide­al for high-vol­ume appli­ca­tions.
Appli­ca­tion Cas­es: Com­mon­ly used in sup­ply chain man­age­ment, inven­to­ry track­ing, asset man­age­ment, and logis­tics.
