What is the maximum range of the RFID module?
Maximum read distance of 1.5 meters (4 foot 11 inches) – usually under 1 meter (3 feet) and you can use a single or multi port reader plus custom antennas to extend the read range to longer tag read distances or a wider RFID read zone.
What is RFID and where is it 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.
How many types of RFID systems are there?
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. In the sections below we will explore the frequencies and types of RFID systems.
What are the components of a RFID reader?
Below are the images of three popular RFID Readers – EM18 RFID Reader Module, RC522 RFID Module and PN532 NFC RFID Module. It consists of 2 components (in case of a passive tag). They are Microchip and an antenna.
How does the Radio Frequency Identification ( RFID ) system work?
How Does RFID Work? Radio Frequency Identification (RFID) is the wireless non-contact use of radio frequency waves to transfer data. Tagging items with RFID tags allows users to automatically and uniquely identify and track inventory and assets.
How does a passive RFID ID card work?
2. Passive RFID system: This is the most commonly used type of system that you can find in ID cards, banking cards etc. It consists of passive tags which doesn’t have any battery to power up the chip in the tag. Instead the Reader transmits the RF signals which are detected by the tag.
What’s the difference between RFID and barcode technology?
The question of RFID vs. barcode has often been described in terms of the past vs. the future, with partisans of both technologies keen to prove that theirs is the best option. Generally speaking, there is a lot of overlap between RFID and barcode, as they both try to solve similar problems in asset-heavy industries.
