When using a NFC standard loop coil antenna, sized about 4x4 cm, the .

It is possible to increase the read range by creating a much larger loop in the reader antenna. A larger tag antenna would increase the read range only slightly. Of course, if you want a read range of longer than 3 feet, you should consider using passive ultrahigh-frequency (UHF) RFID. When using a NFC standard loop coil antenna, sized about 4x4 cm, the theoretical maximum working distance is 20 cm. In practice, the range for reliable communication is much smaller, usually about 5 cm (4 times smaller).

In writing this article I found that both cards and readers appear to resonate anywhere between 13.5 and 15 MHz, with the majority being measured at about 14 MHz.

So far, my understanding is that there are a few main factors in the read distance: Size/shape of the antenna on the NFC reader. Size/shape of the antenna on the NFC chip. Power output of the reader. Power draw of the NFC chip. What is the scan distance of an NFC tag ? In short, typically between 1cm and 5cm if the NFC tag is being scanned with a mobile phone. A number of factors will affect the performance. An NFC Pro tutorial looking at what factors affect the scan or reading distance of an NFC tag. Includes a simple demonstration of the scan distances of two smaller tags using both an.

Typically limited to about 4 cm, the NFC range defines the maximum distance over which two NFC-enabled devices can interact. This limited range is not a drawback but rather a design choice that enhances security and ensures that interactions are deliberate and controlled. The Size of an RFID/NFC Antenna Defines the Operating Distance. In general, the larger your antenna size, the longer the reading distance. Similarly a smaller antenna will give you a shorter read range. However, it’s best to attempt to match the tag and the reader antenna geometries for maximum efficiency.NXP reference boards are tuned for optimal performance in air or with metal surfaces at distance bigger than 2 – 3 cm (distance is depending on antenna dimension).

Near Field Communication (NFC) reading distance is a technology used for short-range communication by a device, and generally has a working distance ranging from a few centimeters to a few.It is possible to increase the read range by creating a much larger loop in the reader antenna. A larger tag antenna would increase the read range only slightly. Of course, if you want a read range of longer than 3 feet, you should consider using passive ultrahigh-frequency (UHF) RFID.
