RFID tags can be grouped into three categories based on the data they communicate with. In general, RFID systems operate in the range of 30 kHz to 300 kHz and have a read range of up to 10 cm. The data read rate is slowed down to a maximum of 1.5 m / s (1,000 ms) and at least 2 m (2,500 ms).
The LF RFID tags have longer wavelengths and a read range of up to 10 cm as well as a data read rate of 1.5 m / s (1,000 ms). They perform better than other types of RFID tags because they have higher data - read rates and lower latency, but also because metals and liquids can interfere with their transmission. The LF RFID tag has a longer wavelength and has an average read time of 2 m (2,500 ms) and a maximum read speed of 3 m / s (3,200 ms) or 2.2 m per second.
In applications where an RFID label is applied to a metal substrate, such as the inventory of beer barrels or cars, it can be used in a wide range of applications.
RFID technology is becoming increasingly widespread in a number of industries, and there are different types of applications that are uniquely suited to each industry. HF RFID tags have a longer read-out time than NFC and are therefore well suited for cataloging from library media to tracking wristbands in amusement parks. NFC has the advantage of working with a much lower performance than RF tags and being able to be read for longer.
RFID tags are classified according to their ability to communicate at a low, high, and ultra-high level (RFID tag is classified as high-frequency tag (HF) and low power RFID tag (low power).
If you are considering introducing RFID technology, we will take a look at what it is, how it works and how it can help you. Below we have listed some of the most common uses of RFID technology and their advantages and disadvantages.
RFID, which stands for Radio Frequency Identification, is the use of radiofrequency technology (RF) to identify an object. The transmission and reception process is carried out via an RFID system consisting of RFIDs, tags, readers, antennas and transceivers. A transceiver reads radio frequencies and transmits them to a processing device such as an RFID tag or transponder.
Radio Frequency Identification (RFID) involves the transmission of information and the identification and tracking of an object by connecting an RFID transponder or tag to the object in question.
As usage increases, the need to reduce the energy consumption and size of tags while maintaining and maximizing the distance at which they can be detected increases. As shown in Figure I below, the reader is used to query the tag, and information is sent back to it. The day can then be seen from a distance of up to 1,000 meters, as shown in Figure II below.
Similar to scanning barcodes, RFID technology enables warehouses and distributors to track their inventory without human intervention. Similar to a barcode, the reader recognizes an RFID tag attached to an inventory item and queries the tag for information. Instead of scanning the barcode or label, it uses weak radio frequencies to transmit its data.
This makes it ideal for harsh environments and applications where reading barcodes can be difficult. Some frequencies are used for passport and security applications that do not require large read ranges.
Large UHF tags can reach a reading range of up to 30 metres under ideal conditions, passive UHF tags can read up to 50 metres in ideal weather conditions. Longer read ranges lead to better performance for applications such as passports and security applications, as well as for other applications.
These frequencies are used for applications that typically require more than one meter of reading range. Such active tags are often used in real-time positioning systems (RTLS) to track the location of objects such as cars, vehicles, and other electronic devices, as well as for security applications.
In passive RFID solutions, the reader and its antenna send a signal to the day, and this signal is used to reflect the performance of the radio signal back to a reader. The read range is shorter than with active tags and is limited by the energy reflected back into the readers by the signal, commonly referred to as the "tag backscatter."
Radio Frequency Identification (RFID) is a method of transmitting data for automatic identification and tracking of tags attached to objects. This means that a large number of objects can be connected or even embedded to RFIDs such as mobile phones, tablets and other devices.
RFID systems consist of a label reader, also known as a scanner, and a barcode reader. Just like barcodes, the RFID reader stores the information contained in an RFID chip in a database. The distance that RFID tags can travel within visual range is limited, as the barcode must be matched with an optical scanner for this to wor
