High-Tech Electronic Solutions Ltd as solutions provider and development experts, recognises the key role Radio Frequency Identification (RFID)
technology play and have developed number of systems based on this technology to help those who seeking to identified and track their assets at any
point along the supply chain or to track their mobile assets.
A basic RFID system contains of the three elements:
Transponder/Tag
Reader/Writer
Software
These three elements combined enable the procedure of identifying, tracking and recording information on an object.
Radio Frequency Identification (RFID) is the most common type of electronic identification systems. These systems are electronic data storage devices in which a coded identification word is stored in a machine-readable (and possibly writable) tag, which uniquely identify an object. Tags exist in many forms and appear on such items as luggage, device, machine, train, car, fish, cow, pet, or human. Tags might be used in identifying or collecting information on the host to which they are attached. RFID tags can be readable from a distance using remote tag reader devices.
RFID systems can be categorized according to the following parameters: Frequency range Typical RFID systems use frequencies in the LF, HF,UHF and up to the microwave band.
LF or Low Frequency is in the 100-500 KHz frequency band and provides short to medium read range at a low reading speed. Its advantages are its ability to penetrate obscuring materials and it is inexpensive compared to other frequencies.
HF or High Frequency ranges from 10-15 MHz; typically 13.56 MHz and provides short to medium reading range at medium reading speed. It’s potentially inexpensive and has moderate penetration in obscuring materials.
UHF or Ultra High Frequency has a comparatively lengthy reading range and is available in 860-950 MHz frequency band. It also has high reading speed and is expensive as compared to the other frequencies.
Microwave Frequency is found in 2.4-5.8 GHz frequency band and has a medium reading range with moderate penetration ability in obscuring materials. It’s relatively expensive as compared to LF and HF.
Active/passive: Whether the tag contains a power source or not. Active tags allow bigger operational range, whereas passive tags cost less and have longer lifetime. Chip/chip less: Whether there is an embedded integrated circuit (IC) in the tag. Microchips allow greater functionalities (R/W, on-tag processing). Conventional/low cost: The industry is pushing towards the achievement of low cost tags that will overcome limitations due to the cost of integrating RF tags.
