NFC card’s purpose, use, and examples

NFC (Near Field Communication) Cards are designed for contactless data exchange and transactions. Though it sounds like WIFI or Bluetooth but there is a difference that is, when you are using Bluetooth, first it needs to be paired with and in case of WIFI it needs password to connect that is slightly time taking process. But in NFC method within no time, it would get connected to the other device if they also had this feature. NFC cards purposes include:

1. Payments: Make payments by tapping the card on an NFC-enabled terminal.
2. Data sharing: Exchange information like contacts, files, or URLs between devices.
3. Identity verification: Use as identification cards for access control or authentication.
4. Public transportation: Serve as tickets or passes for public transit systems.
5. Loyalty programs: Store and redeem points or rewards.
6. Access control: Grant access to secured areas, events, or buildings.
7. Health records: Store medical information for emergency situations.
8. Hotel room keys: Replace traditional keys with contactless room access.

To use an NFC card:

1. Ensure the card is enabled for the desired function (e.g., payments or data sharing).
2. Hold the card within range (typically 1-10 cm) of the NFC reader or device.
3. Authenticate if necessary (e.g., enter a PIN or sign a receipt).
4. Wait for confirmation (e.g., a beep, light, or message).
