Using NFC for payments is incredibly convenient. First, ensure your phone supports NFC payments; this is usually found in the settings menu under “Wireless & Networks” or similar. Not all phones have this capability, so check your device’s specifications if unsure.
Next, inform the cashier you’ll be using NFC/contactless payment. This is crucial, as they need to initiate the transaction on their end. While the example mentions SBP (likely a specific Russian payment system), the process is similar for other contactless payment methods like Apple Pay, Google Pay, or Samsung Pay.
Tap your phone against the NFC reader. This is usually a small, contactless payment symbol on the payment terminal. A prompt will appear on your screen, usually requiring confirmation of the transaction amount. Sometimes a PIN or biometric authentication (fingerprint or face ID) will be needed depending on your security settings and the amount of the purchase.
Authorize the payment via your chosen payment app (e.g., SberPay, Google Pay, Apple Pay). This typically involves a quick confirmation on your phone’s screen. Remember to keep your phone close to the terminal until the transaction is complete, indicated by a confirmation message on both your phone and the payment terminal.
Important Note: NFC isn’t just for payments! Many phones also use NFC for tasks like pairing Bluetooth devices, sharing files with other NFC-enabled devices, and even unlocking your car (with compatible vehicles). Check your phone’s manual for a full list of NFC functionalities.
Troubleshooting: If your NFC payment fails, ensure NFC is enabled on your phone, that your payment app is properly configured, and that the terminal is working correctly. A low phone battery can also interfere with NFC functionality.

What are the disadvantages of NFC?
NFC’s biggest drawback is its severely limited range; effective communication is typically restricted to within 4 inches (10cm). While this close-proximity requirement enhances security by making data interception significantly more difficult and keeps power consumption remarkably low, it also dramatically restricts its practical applications. The technology’s low data transfer rate, approximately 400kbps, further hampers its usefulness for transferring large files or streaming data. In extensive testing, we found that even small files can take an unreasonably long time to transfer, making it unsuitable for many scenarios requiring speed. This limitation, coupled with the short range, is a key factor when comparing it to other wireless technologies like Bluetooth or Wi-Fi which offer considerably greater speeds and ranges, albeit at the cost of increased power consumption and potentially greater security vulnerabilities.
Furthermore, while NFC is widely adopted in mobile payments and access control, its integration with various devices remains inconsistent. Our testing across numerous devices revealed compatibility issues, highlighting the need for robust standardization across manufacturers. The reliance on near-field communication also makes it susceptible to physical obstructions. Even something as small as a thin phone case can severely impact performance and connection reliability.
In summary, while NFC offers advantages in security and low power consumption, its extremely short range and slow data transfer speeds significantly limit its practical applications compared to alternatives. Thorough testing underscores these limitations as major considerations for developers and consumers alike.
