It feels simpler than joining Wi-Fi or pairing a Bluetooth device because there may be no network name, password, or visible connection process.</p> <p>The technology behind many of these taps is <strong>Near Field Communication (NFC)</strong>. The useful mental model is that NFC creates a very short-range radio interaction between compatible devices. The tap itself is not transferring information through physical contact. Bringing the devices close together puts their NFC antennas in a position where radio communication can take place.</p>
