NFC technology
NFC stands for Near-Field Communication. It is a contactless communication technology that enables two NFC-compatible devices to exchange data within a short distance. Common examples of NFC-enabled items include tags, cards, stickers, wristbands, etc.
Due to its security, versatility, and simple setup, NFC is ideally suited for a broad range of industries and environments. Nowadays, NFC cards are most widely used in mobile payment systems (where you tap your phone into a reader to make a payment) for their convenience and high levels of security. NFC cards can also be used as virtual business cards to share contact information, as "keys" to open doors, or as contactless transport cards for public transportation.
After the global outbreak of COVID-19, the NFC industry has seen dramatic growth in its value and proved its promising potentials in the future of contactless payment.
How NFC cards work
NFC cards are passive devices, drawing power from the device that reads them through magnetic induction. When the reader gets close enough (from a touch to a few centimeters), it energizes the tag and transfers the data. For example, you could hold your NFC card behind your phone (assuming your phone supports NFC), then open the NFC card reader app on your phone to read the card. Your phone will automatically open the link is written to the card.
Data NFC cards can hold
There are various types of data that an NFC card can hold:
Text
URL/URI
File
Email
Phone number
SMS
and many more
NFC cards are rewritable, meaning that you can replace what was written to an NFC card with something else. However, they cannot hold multiple data items.
How to get an NFC card
NFC cards are very popular and easy to get nowadays. You can purchase NFC cards from any local NFC store at a relatively affordable price or place an order on Amazon, usually sold in bulk. For this contest, we will provide you with an NFC card to customize.
