NFC (Near Field Communication) tags are small electronic devices that can store and transmit information wirelessly using radio waves. NFC tags are typically used to trigger an action on a mobile device when it is brought into close proximity with the tag.
Here are some common use cases for NFC tags:
- Mobile payments: NFC tags are used to enable mobile payments by allowing users to tap their phone on a payment terminal to make a transaction.
- Access control: NFC tags can be used to control access to a building or room by requiring users to tap their phone on an NFC tag to unlock a door.
- Marketing and advertising: NFC tags can be embedded in promotional materials, such as posters or flyers, to provide users with additional information or a call-to-action when they tap their phone on the tag.
- Product authentication: NFC tags can be used to verify the authenticity of a product by allowing users to tap their phone on the tag to access information about the product's origin and authenticity.
- Smart home automation: NFC tags can be used to automate tasks in a smart home, such as turning off the lights or adjusting the thermostat, by allowing users to tap their phone on a tag to trigger the action.
