Different Types of NFC Cards | Tapt

Ever tapped your credit card to pay or used an ID badge to enter work? That's NFC in action. This nifty tech stands for Near Field Communication. The short range wireless technology is revolutionising how we interact with each other and with the world at large. NFC cards serve a range of different functions - payment processing, access control and data transfer are just a few applications they are used for. 

1. NFC Payment Cards

The most common use of NFC technology is in payment cards like your credit or debit card. With a simple tap, you can complete a transaction in seconds. These cards, issued by banks and linked to major payment networks like Visa and Mastercard, contain a chip that securely stores your payment information. When you tap the card against a payment terminal, the chip instantly communicates your transaction details, making checkout quick and effortless.

Security is of utmost importance with payment cards and they use encryption technology to safeguard your data. NFC also adds another layer of protection as someone cannot skim your card remotely. Many smartphones now include NFC payment capabilities for Apple Pay, Google Pay and Samsung Pay which  turns your smartphone into a virtual wallet.

Most of the access control cards are rewritable, which allows administrators to update access rights remotely without issuing new cards.

Transport cards can often be reloaded. Users can add credit online or at kiosks. In some systems, there may even be auto-reload options so as to never run out of credit. Transport cards often offer benefits, including discounted fares or transfer privileges, that help transit authorities improve their services. With data gleaned from these cards, transit authorities can optimise their offerings.

4. NFC Loyalty Cards

NFC loyalty cards provide businesses with invaluable data. By tracking consumer purchasing behaviours and preferences, these cards help companies tailor their offerings and marketing to match customer preferences and needs.

5. NFC Event and Venue Cards

Festivals, concerts and sports arenas often utilise NFC cards at events for multiple use like  ticket purchases or access passes. Event NFC cards are harder to fake than paper tickets and some venues even use wristbands with embedded NFC chips in place of cards for expedient entry.

These cards allow customers to store funds for food and merchandise purchases, helping to streamline transactions while reducing cash handling. Event organisers can personalise event cards for attendees with schedules and maps for easy navigation, while attendees may tap their cards against info stations to receive personalised guidance.
