What is the UHF RFID reader for?

What is the UHF RFID reader for?

A UHF RFID reader is a device using an Ultra-High Frequency (UHF) range, between 840 MHz and 960 MHz. Its extended read range compared to HF NFC readers enables one reader to interact with many tags at the same time, at a very high speed, within distances of tens of meters.

Is UHF an RFID?

The Ultra High Frequency (UHF) band is the frequency range from 300 MHz to 1 GHz. RFID systems that operate in this frequency band are called Ultra High Frequency (UHF) RFID Systems. UHF RFID tags/readers usually operate at 433 MHz and from 860 to 960 MHz.

How does a tag in a UHF RFID system receive power?

The system has three major components: reader, antennas and tags attached at the unit under test. RFID tags can store data and modify it according to RF signal from the antennas connected to the readers. The passive tag itself can harvest power from the RF energy of the reader signal.

What is difference between UHF and RFID?

Unlike HF RFID, UHF RFID offers near-field and far-field read ranges. Near-field RFID operates similarly to HF RFID, where the antennas generate a magnetic field. Since the tag is closer to the antenna, near-field UHF has a narrower field of view and a shorter read range (comparable to HF RFID).

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.

How did my card get skimmed?

It can happen if you use an ATM with a card skimming device installed, when you’re paying for something on a dodgy website, and your bankcard details can even be skimmed when your cards are inside your wallet.

Can credit cards be skimmed remotely?

Thieves armed with scanning devices could indeed read your card information by intercepting its RFID signal, stealing your information as long as they were close to you. Thieves could steal information even if your RFID-emitting card was tucked into your wallet, purse or pocket.

What is the typical use of passive UHF technology?

Great examples of passive UHF tags are here and here. Passive Microwave Frequency (2.45 GHz) tags are the least common within the passive family, however, they are used for inventory tracking and various applications that do not require long read ranges but have a need for very fast data transfer rates.

Does UHF go through walls?

UHF radio waves generally only go as far as line of sight. Anything in the way of your sight will also interfere with frequency range, such as buildings, tall trees or any other obstruction. The transmission is high enough to penetrate through building walls, making indoor reception a possibility.

Can RFID read through wood?

An RFID tag’s signal weakens the father away it is from a reader, so if there is not a strong signal from a nearby antenna, then the energy would not penetrate the wood. I would say you should be able to read a tag through a three-quarter-inch-thick piece of particle board, as long as it isn’t very wet.
