Contactless Technology
Contactless technology refers to systems and devices that enable communication or transactions without physical contact, typically using radio-frequency identification (RFID), near-field communication (NFC), or Bluetooth. It is widely used in payment systems, access control, and data transfer applications. This technology enhances convenience, speed, and hygiene by eliminating the need for direct touch or insertion.
Developers should learn contactless technology to build modern applications in fintech, IoT, and smart devices, where seamless user experiences are critical. It is essential for implementing features like mobile payments, secure building access, and automated inventory tracking. Understanding this concept helps in integrating hardware and software for real-world solutions that prioritize efficiency and safety.
