The versatility of the protocol makes it an ideal bridge between the physical world and digital services. This frequency band allows for data transfer rates of 106, 212, or 424 kilobits per second, which is sufficient for transmitting keys, identifiers, or small packets of information.
Unlike Bluetooth or Wi-Fi, which can connect over several meters, NFC is designed for proximity-based engagement, ensuring a secure and intuitive user experience. Users can write URLs or commands to these tags, turning a static poster into an interactive gateway, provided the encoding format is universally recognized by the operating system.
