NFC-enabled credit and debit cards were introduced in the early 2000s, allowing customers to make payments by simply holding their card near a payment terminal.
nfc tag scan distance
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.

I'm trying to understand how to improve the reading distance of an NFC system. 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.
I want to read a NFC tag at a distance of 1m from my NFC enabled smartphone. Is it possible to do so by enhancing the antenna of the NFC tag (not the one on the phone). Size of the NFC tag is not an issue, and so we can use a bigger/complex antenna with power supply through battery (active tags).
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. 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.
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).

Maximising NFC range starts with optimal tag and reader positioning. Ensuring a clear, unobstructed path between them can significantly improve connectivity. Additionally, environmental factors such as the presence of metals or .Near Field Communication (NFC) is a short-range wireless communication technology that has revolutionized how devices interact in various industries, from payments to data sharing. This NFC tutorial guide covers protocol stack, working principles, frame structure and different communication modes.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).It is possible to increase the read range by creating a much larger loop in the reader antenna.
