What are the types of RFID reader?
Each RFID type can be either active (powered), passive (un-powered) or semi-passive (battery-assisted).
- Low-frequency (LF) RFID tags: 30 KHz to 300 KHz.
- High-frequency (HF) RFID tags: 3 to 30 MHz.
- Ultra-high-frequency (UHF) RFID tags: 300 MHz to 3GHz.
- Active, passive and semi-passive RFID tags.
What is a UHF RFID reader?
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.
What are the three frequency bands typically used for RFID tags?
The industry has worked diligently to standardize three main RF bands – low frequency, high frequency, and ultra-high frequency. Most countries have assigned the 125 or 134 kHz areas of the spectrum for low-frequency RFID systems, and 13.56 MHz is generally used around the world for high-frequency RFID systems.
What is configuration card?
A configuration card is a specially formatted smart card provided by Honeywell that is coded to turn on/off features in a smart card reader. As requests for specific configuration cards become popular, Honeywell Product Management will release configuration cards as parts.
What is an RFID reader?
What is an RFID reader? RFID tagging is an ID system that uses small radio frequency identification devices for identification and tracking purposes. An RFID tagging system includes the tag itself, a read/write device, and a host system application for data collection, processing, and transmission.
How to use RFID to open a door?
You can use an RFID system to open a door. For example, only the person with the right information on his card is allowed to enter. An RFID system uses: >> tags attached to the object to be identified, in this example we have a keychain and an electromagnetic card.
What is an RFID tagging system?
An RFID tagging system includes the tag itself, a read/write device, and a host system application for data collection, processing, and transmission. In simple words an RFID uses electromagnetic fields to transfer data over short distances. RFID is useful to identify people, to make transactions, etc… You can use an RFID system to open a door.
How to read RFID on Arduino with Arduino IDE?
This code will be available in Arduino IDE (after installing the RFID library). Then, open the serial monitor. You should see something like the figure below: Approximate the RFID card or the keychain to the reader. Let the reader and the tag closer until all the information is displayed.
