Radio Fre­quen­cy Iden­ti­fi­ca­tion (RFID) tech­nol­o­gy is wide­ly used to track and iden­ti­fy objects using elec­tro­mag­net­ic fields. There are many types of RFID tags, each designed for spe­cif­ic appli­ca­tions and envi­ron­ments.

Below is an overview of the main types of RFID tags:

Passive RFID Tags

Descrip­tion: These tags do not have bat­ter­ies and are pow­ered by ener­gy from the RFID read­er sig­nal.
Range: The read­ing range is usu­al­ly short, gen­er­al­ly not exceed­ing 10 meters.
Cost: Usu­al­ly more eco­nom­i­cal than active label­ing.
Appli­ca­tion Cas­es: Com­mon­ly used in inven­to­ry man­age­ment, access con­trol, and sup­ply chain track­ing.

Active RFID Tags

Descrip­tion: These tags are equipped with their own bat­ter­ies, enabling them to trans­mit sig­nals inde­pen­dent­ly.
Range: Enables a longer read­ing range, typ­i­cal­ly exceed­ing 100 meters.
Cost: High­er price due to bat­ter­ies and oth­er com­po­nents.
Appli­ca­tion Cas­es: Com­mon­ly used for track­ing high-val­ue assets, real-time loca­tion sys­tems, and envi­ron­ments requir­ing greater dis­tance.

Semi-passive (or battery-assisted) RFID tags

Descrip­tion: These tags have a built-in bat­tery that pow­ers the tag cir­cuit­ry, but still require an exter­nal card read­er for com­mu­ni­ca­tion.
Scope: The scope is far­ther than that of pas­sive tags, but short­er than that of active tags.
Cost: Prices typ­i­cal­ly fall between those of pas­sive and active label­ing.
Appli­ca­tion Cas­es: Used for appli­ca­tions such as tem­per­a­ture mon­i­tor­ing and envi­ron­men­tal sens­ing.

Low Frequency (LF) RFID Tags

Fre­quen­cy range: Oper­at­ing fre­quen­cy from 125 kHz to 134 kHz.
Range: Short-range read­ing range, typ­i­cal­ly up to 10 cm.
Appli­ca­tion Cas­es: Com­mon­ly used in ani­mal track­ing, access con­trol, and auto­mo­tive appli­ca­tions.

High Frequency (HF) RFID Tags

Fre­quen­cy range: Oper­at­ing fre­quen­cy is 13.56 MHz.
Mea­sure­ment range: The read­ing range is approx­i­mate­ly 10 cen­time­ters to 1 meter.
Appli­ca­tion Cas­es: Wide­ly used in con­tact­less pay­ment sys­tems, library book track­ing, and smart cards.

Ultra-High Frequency (UHF) RFID Tags

Fre­quen­cy range: Oper­at­ing fre­quen­cy is between 300 MHz and 3 GHz, typ­i­cal­ly around 860–960 MHz.
Range: Reads dis­tances from sev­er­al meters to 12 meters or more.
Appli­ca­tion Cas­es: Ide­al for sup­ply chain man­age­ment, inven­to­ry track­ing, and large-scale asset man­age­ment.

Dedicated RFID tags

Descrip­tion: These labels are designed for spe­cif­ic appli­ca­tions, such as high-tem­per­a­ture envi­ron­ments, harsh con­di­tions, or embed­ded in prod­ucts.
Appli­ca­tion Cas­es: For exam­ple, it can be used in phar­ma­ceu­ti­cal label­ing, food safe­ty, and indus­tri­al appli­ca­tions.
