What are the different types of RFID NFC protocol supported by TRF7970A?
What are the different types of RFID NFC protocol supported by TRF7970A?
The TRF7970A device is an integrated analog front end (AFE) and multiprotocol data-framing device for a 13.56-MHz NFC/RFID system supporting all three NFC operation modes – reader/writer, peer-to-peer, and card emulation according to ISO/IEC 14443 A and B, Sony FeliCa, ISO/IEC 15693, NFCIP-1 (ISO/IEC 18092), and NFCIP- …
What is the frequency of RFID?
RFID TAG CHARACTERISTICS OVERVIEW BASED ON FREQUENCY
| Frequency Bands | Antenna | Read Range |
|---|---|---|
| Very High Frequency (VHF) 433 Mhz – Active Tags | Internal Custom Design | High 1-1000 feet |
| Ultra High Frequency (UHF) 860 MHz – 960 MHz | Single or Double Dipole | Medium 1-30 feet |
| Microwave Frequency 2.45 GHz & 5.4 GHz | Single Dipole | High 1-300 feet |
What is RFID Techtarget?
Radio-frequency identification (RFID) technology enables remote and automated gathering and sending of information between RFID tags or transponders and readers using a wireless link. RFID readers may be handheld units or fixed units connected to a remote computer system.
How many RFID tags can be read at once?
Technically, all RFID readers can interrogate only one tag at a time. If two tags are sending signals to a reader simultaneously, there is no way for the device to distinguish one from another.
What’s the difference between RFID and NFC?
While RFID technology can be used over long distances, NFC technology is limited to small distances. RFID tags can generally be scanned at distances of up to 100 meters and do not require a direct line of sight to the reader.
Can transmit data at a rate of either 106212 or 424 kbps?
NFC technology data transfer The data transfer rate may be either 106, 212 or 424 kbps. The application itself sets up the initial communication speed, but it may be changed later dependent upon the communication environment and the requirements.
Why is 13.56 MHz used?
In the middle we have the frequency 13.56 MHz. One of the standard frequencies used world wide for industrial, scientific, and medical uses. This frequency is used for a faster etching process, but has to be fine tuned for each piece of material that would be placed in the chamber.
What is RFID virus?
An RFID virus is malicious code inserted into an RFID tag to alter or corrupt data in an RFID (radio frequency identification) system. The deliberate creation and spreading of this type of virus is called RFID hacking.
Can RFID reader read any tag?
What is the read range of your RFID tags?
Our High Frequency 13.56 MHz RFID tags have a read range of up to 1 to 12 inches, uses NFC protocol, and has a larger memory for storing data.
What are the different types of RFID tags?
The high frequency 13.56 MHz RFID tags are available in various models such as metal tags, wrist band tags, thin RFID cards, mount on metal tags, round paper tags, clear thin tags, passive RFID tags , disc tags, label tags, water proof tags ,livestock ear tags, and laundry tags.
What is the MIFARE® RF interface (ISO 14443A)?
The aim is to provide the required understanding of the MIFARE® RF interface (ISO 14443A) to design application specific antennas and matching circuits to achieve the best performance for a communication with a contactless MIFARE® card.
