distance between rfid tag and reader Is there a way to calculate/estimate the physical distance to a long-distance passive RFID tag when reading it with a tag reader? E.g. to determine the order of books in a shelf, or telling if one object is close or far away. There so many factors. If the card is a high frequency card that your phone can .

The read range of RFID tags refers to the maximum distance at which the readers can successfully capture the data from the tags. Understanding the read range is crucial for implementing RFID systems effectively and optimizing their performance. Is there a way to calculate/estimate the physical distance to a long-distance passive RFID tag when reading it with a tag reader? E.g. to determine the order of books in a shelf, or telling if one object is close or far away.
Let’s take a brief look at the main factors that affect the read distance of RFID: The “voice” of the RFID reader and the “ear” of the RFID tags. The transmission power of RFID reader is the key factor to determine the reading distance of RIFD chip.
The distance from which a tag can be read is called its read range. Read range depends on a number of factors, including the frequency of the radio waves uses for tag-reader communication, the size of the tag antenna, the power output of the reader, and whether the tags have a battery to broadcast a signal or gather energy from a reader and . Reader-Tag Distance: The distance between the RFID reader and the tagged object can impact read performance. If the distance between the reader and the tag is too far, the tag’s response may be weak or non-existent.RFID is wireless technology that uses Radio Frequency (RF) electromagnetic energy to carry information between an RFID tag and an RFID reader. Some RFID systems will only work over a few inches (or centimetres) while others may work over 100 metres (300 feet) or more. Low Frequency RFID: has the shortest read distance, about 10 centimeters between the reader and the tag. Low frequency covers ranges from 30 to 300 KHz. High Frequency RFID: The read distance ranges from 10 centimeters to 1 meter. Operates in a frequency range from 3 to 30 MHz. Ultra-High Frequency RFID:
Generally speaking, the higher the frequency the further the read range. However, there are many factors such as antenna size, environmental factors, line-of-sight, and whether the tags are passive or active that can affect the working distance between tag and reader. I understood that all methods to get distance from RFID are more or less at a “research” level. (is it still true ?) I know 2 of these methods: The “RSSI method”, that measure the signal strength, and the “radar” method, that measure the time between signal emission and Tag answer reception.An algorithm has been developed to determine the distance between an RFID-reader and a tag involved in the communication. Although based on wideband TOF (time of flight) algorithm, this algorithm can be applied for existing tags without the need for modification. The algorithm can be The read range of RFID tags refers to the maximum distance at which the readers can successfully capture the data from the tags.
