What are the two types of RFID?

RFID systems and frequencies RFID systems can be broken down by the frequency band within which they operate: low frequency, high frequency, and ultra-high frequency. There are also two broad categories of systems—passive and active RFID.

How many types of RFID are there?

RFID tags can be grouped into three categories based on the range of frequencies they use to communicate data: low frequency (LF), high frequency (HF) and ultra-high frequency (UHF).

What are examples of RFID?

The most common RFID applications in hospitals are inventory tracking, control access, staff and patients tracking, tracking tools, tracking disposable consumables, tracking large/expensive equipment, laundry tracking, etc.

What is UHF RFID used for?

Active UHF RFID applications are frequently used in industries like oil and gas, transportation, and vehicle tracking. Because active tags beacon, they are easier to read while moving and are ideal for tracking cargo containers and vehicles.

Why RFID is used?

RFID tags are a type of tracking system that uses radio frequency to search, identify, track, and communicate with items and people. Essentially, RFID tags are smart labels that can store a range of information from serial numbers, to a short description, and even pages of data.

What is the difference between HF and UHF?

UHF systems are known for generating long read ranges, up to twelve meters (forty feet), whereas HF systems carry a much shorter read range of approximately one meter (three feet). UHF allows for a faster data transfer rate, up to 20 times the range and speed of HF systems.

Which is faster RFID or NFC?

NFC is best used to securely transfer a range of data over short distances, hence its prevalence in access control and payment applications. On the other hand, RFID is more suited to faster moving environments with lots of moving parts and is most often used for vehicle access control and asset management purposes.
