Q&A

Are there different types of RFID?

Are there different types of RFID?

There are a variety of RFID tags on the market today, differentiated by frequency range (low, high and ultra-high). Each RFID type can be either active (powered), passive (un-powered) or semi-passive (battery-assisted).

What are the three types of RFID?

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).

Are all RFID cards the same?

Not all RFID cards are created the same. Most RFID cards that are some kind of “smart” (i.e. contactless bank cards, subway tickets) conform to ISO/IEC 14443 standard that mandates the use of ~13.5MHz carrier to communicate between the reader and the card.

What is the difference between RFID?

The main difference to RFID is that a NFC device can act not only as a reader, but also as a tag (card emulation mode). In peer-to-peer mode, it is also possible to transfer information between two NFC devices. NFC systems operate on the same frequency as HF RFID (13.56 MHz) systems.

What is the most common RFID frequency?

RFID TAG CHARACTERISTICS OVERVIEW BASED ON FREQUENCY

Frequency Bands Antenna
High Frequency (HF) 13.56 MHz Induction Coil flat 3-9 turns
Very High Frequency (VHF) 433 Mhz – Active Tags Internal Custom Design
Ultra High Frequency (UHF) 860 MHz – 960 MHz Single or Double Dipole
Microwave Frequency 2.45 GHz & 5.4 GHz Single Dipole

What are the two types of RFID?

RFID systems can be broken down by the frequency band within which they operate. There are also two broad categories of systems—passive and active RFID.

What is the maximum range of RFID?

Active RFID systems typically operate in the ultra-high frequency (UHF) band and offer a range of up to 100 m. In general, active tags are used on large objects, such as rail cars, big reusable containers, and other assets that need to be tracked over long distances.

How far can RFID be tracked?

Far-range UHF RFID tags can read at ranges as far as 12 meters with a passive RFID tag, whereas active tags can achieve ranges of 100 meters or more. The operating frequency of UHF RFID tags ranges from 300 MHz to 3 GHz, and UHF tags are the most vulnerable to interference.

Can phones read RFID?

Yes, you can use your phone as RFID tag. For Android or Windows phones you enable NFC. In case of an Apple you need to enable Bluetooth. Nowadays, the smart phone can be used as RFID tag as well.

Can cell phones read RFID tags?

Do cell phones use RFID?

Phones as RFID Cards What’s interesting, though, is that this tech is not limited to access cards and readers: Most modern smartphones have an RFID chip inside them. Moreover, this RFID chip adheres to the NFC standard, meaning that all smartphones these days can operate as NFC cards.
