The Green Bay Packers snuck into the playoffs as the NFC's last Wild Card team with a 9-8 record. The Pack now heads to Dallas to take on the 12-5 Cowboys, who overtook the Eagles in the final .
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.It is possible to increase the read range by creating a much larger loop in the reader antenna.

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). 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).
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 . In the following sections, we will delve deeper into the factors affecting NFC range, explore the limitations of NFC, and examine techniques for extending its range.

The most crucial part about designing an NFC reader is its antenna. The optimum read range and reliability of your NFC device highly depends on the underlying antenna design. Planning Your Requirements Is Always a Good Way to Start
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. NFC devices operate at the same frequency as high frequency RFID readers and tags — 13.56 MHz. But unlike RFID devices and tags, NFC does not have a range from 25 meters to 100 meters. Instead, NFC takes advantage of the short read range limitations of .
The NFC XL Reader is the only one that allows you to read and write NFC Tags and Cards up to a distance of 15 cm. It supports NFC Forum types 1-4 and the P2P and HCE protocols.
