The Technology Behind NFC Triggers
NFC triggers operate on the principles of near-field communication, a set of communication protocols that enable two electronic devices to establish communication by bringing them within a few centimeters of each other. This technology is based on radio-frequency identification (RFID) standards and operates at a frequency of 13.56 MHz. NFC triggers are embedded within digital signage systems, often in the form of small chips or tags that can be programmed to perform specific actions when activated by an NFC-enabled device. The interaction is initiated when the NFC device, such as a smartphone, enters the electromagnetic field generated by the NFC trigger. This proximity-based communication allows for the exchange of data, which can be used to trigger a variety of responses, such as displaying personalized advertisements, providing additional product information, or even processing payments. The simplicity and versatility of NFC technology make it an ideal solution for enhancing the interactivity of digital signage systems.
