All You Need to Know About NFC Tags
What is NFC?
Near Field Communication (NFC) is a short-range wireless technology that enables data exchange between devices in close proximity. It's widely used in contactless payments, public transport, and access control.
What is an NFC Tag?
An NFC tag is a small device with a microchip and antenna that stores and transmits data when near an NFC-enabled device like a smartphone. Tags come in various forms—stickers, wristbands, cards—and can be programmed with information such as URLs, contact details, or product data.
How Does It Work?
NFC tags are powered by the electromagnetic field of a nearby device. Once activated, they send stored data back to the device, which can then trigger actions like opening a website or saving a contact.
Applications
Marketing: Direct users to websites or promotional content.
Access Control: Secure entry to buildings or restricted areas.
Transport Ticketing: Enable contactless fare payments.
Healthcare: Track patient data and medication schedules.
Summary
