NFC Tags: Unlocking Everyday Convenience with a Tap

What Are NFC Tags?

Near Field Communication (NFC) tags are small, wireless data transmission devices jo radio waves ka use karke short distances pe data transmit karte hain. Typically, NFC tags don’t require power or batteries. Instead, they are powered by the NFC reader (such as your smartphone) that interacts with them. Once scanned, NFC tags can trigger a wide variety of actions on a device, chahe wo ek website kholni ho, message bhejna ho ya payment complete karna ho.

NFC technology is widely available in smartphones, tablets, smartwatches, and other devices, making it an easily accessible tool for quick, seamless interactions.

How Do NFC Tags Work?

NFC works over a very short range—around 4 cm or less. Jab bhi aapka NFC-enabled device pass aata hai, it generates a small electromagnetic field that powers the tag. The tag then sends back the data to your device, triggering whatever action you’ve set up.

The process is instant and effortless, aur koi manual pairing ki zaroorat nahi hoti.
