Near Field Communication, commonly called NFC, is a wireless communication protocol that allows two electronic devices, typically smartphones, laptops, tablets, other devices, and a terminal, to establish communication by bringing them within 4 cm (1.6 in) of each other. This contactless technology enables users to perform simplified transactions, data exchange, and wireless connections.
Let us understand more about NFC and the most common ways to accept NFC payments.
Origin and Development of NFC: NFC was initially developed in 2002 by Philips and Sony to provide a wireless data communication system that was easy to use and reliable.
Mechanism of NFC: NFC operates at 13.56 MHz and transfers data at up to 424 kbit/s. NFC is compatible with existing passive RFID (Radio-frequency identification) infrastructures.
Types of NFC Communication: There are three modes of operation for NFC – reader/writer (e.g., for reading tags in NFC posters), peer-to-peer (e.g., for file transfers), and card emulation (e.g., for making payments).
NFC payments use a wireless connection to transmit information from an NFC-enabled device to an NFC reader.
Device Setup: The first step to using NFC payments is to have an NFC-enabled device. For mobile payments, this often involves adding credit or debit card information to a mobile wallet’s app, such as Apple Pay or Google Pay.
Transaction Initiation: When customers are ready to purchase, they open their mobile wallet app and select the card they wish to use. The app might ask for authentication, like a fingerprint or passcode.
Connection Establishment: Customers hold their NFC-enabled device near the payment terminal or card reader. NFC technology uses radio waves to connect the two devices once they are within a few centimetres of each other.
Data Transmission: Once the connection is established, encrypted payment information is transmitted from the mobile device to the payment terminal.
Transaction Confirmation: The payment terminal sends the information to the payment processor to process the transaction. Once approved, the terminal will send a signal indicating the completion of the transaction.
NFC Payments provide consumers with a quick, handy, and streamlined method to purchase goods and services. By enabling transactions with just a tap of a smartphone or wearable device, they simplify the checkout process and offer a plethora of benefits for both businesses and consumers, such as:
Speed and Convenience: NFC payments are faster than traditional credit or debit card payments and cash transactions. They require no physical contact and do not necessitate entering a PIN, resulting in a more streamlined checkout process.
Security: NFC payments are secure as they use encryption to protect the customer’s payment information. Moreover, the customer’s card number is never shared with the merchant, reducing the risk of card information theft.
Versatility: NFC payments are not limited to mobile wallets. Contactless cards, key fobs, and NFC-enabled wearable devices can also be used.
Hygienic: In the wake of the COVID-19 pandemic, contactless payments have been favoured due to their hygienic nature, avoiding physical contact between individuals and shared devices.
