What is the use of NFC?

nfc

NFC (Near-Field Communication) is a technology that allows contactless transactions using a mobile phone, similar to how we make payments with a credit/debit card by tapping on a machine.

For NFC, no PIN is required. Simply holding your mobile phone near a point-of-sale (POS) terminal is sufficient to complete a transaction.

Additional Uses of NFC:

  • Travel Cards: NFC can be used for ticketing systems, though it’s not widely available in many regions yet.
  • Payment Convenience: Even if you don’t have your physical card, you can make payments using NFC-enabled devices.

NFC FAQ:

How to enable NFC?

  • Link your credit card details in apps like Google Pay or CRED.
  • Enable NFC in your phone’s settings.

Can NFC work on any phone?
No, your phone must support NFC technology and have it enabled in the settings.

How does it work?

  • After linking your credit card in the app, bring your phone near the WiFi symbol on a POS machine to complete the transaction.

What is the working range of NFC?
It works within a range of 5 cm.

Can someone misuse NFC without your knowledge?
No, your phone needs to be unlocked for the transaction to proceed.

Is NFC safe?

  • NFC is safer than Bluetooth due to its short range and added security layers.
  • However, if your phone is lost and unlocked, it could potentially be misused.

What if I have multiple cards?
The default card set in the app will be used for transactions. You can switch to another card if needed.

Benefits of NFC:

  1. No Physical Cards Required:
    Even without a physical card, you can make payments using your mobile phone.

  2. Compact and Convenient:
    People with multiple credit cards don’t need to carry all of them. NFC-enabled devices make managing transactions easier.

  3. Widespread Compatibility:
    Most POS machines (around 95%) now support WiFi or NFC tap payments.

  4. Quick Transactions:
    Payments are fast and hassle-free compared to traditional methods.

Limitations and Controls:

  • NFC must be enabled on both the phone and the bank-issued credit/debit card.
  • It’s a user-friendly alternative to card-tap payments but not yet widely recognized by everyone.

Fun Fact:

Once, after making a payment using NFC, the cashier was amazed and confused about how the transaction happened despite the bill being generated. You might experience similar moments and think, “Why didn’t I know about this sooner?”

Just like UPI is simple and efficient, NFC also simplifies contactless payments.
