Contactless transactions have become a safer, more convenient way to pay for goods and services. Popularised during the pandemic, contactless payments let you use credit or debit cards and compatible smartphones to complete transactions without physical contact.
Smartphone-based payment options make transactions effortless and fast, but many users haven’t yet explored their full potential. A clear understanding of how contactless payments work helps you pay quickly and securely wherever this option is accepted.
Brief Introduction to Contactless Payments
Contactless payment is a quick, secure method of paying without cash. Cards with an embedded chip, such as credit and debit cards, and many smartphones support contactless transactions. To pay, you tap or hover the card or device over the card reader at the point of sale.
These transactions typically do not require entering a PIN for small amounts, which speeds up checkout—useful for tolls, parking, public transport and retail purchases. In India, the Reserve Bank raised the contactless no-PIN limit from ₹2,000 to ₹5,000 to encourage wider adoption.
Benefits to Keep in Mind
Although some people worry contactless payments expose card data to theft, modern contactless systems use encryption and secure communication protocols that make unauthorised access difficult. Tapping a card or using a phone reduces the need to hand over your card or type card details, lowering the risk of card cloning and other forms of fraud.
Contactless payments also reduce processing time compared with manual card entry. When you use a smartphone, you can pay even if you forgot your physical card at home. Smartphone contactless payments often rely on bank-linked payment apps or UPI apps: you scan a merchant QR code and authenticate the payment on your device using an OTP, PIN, or app-based biometric verification.
Mechanism of Contactless Payments
Most non-UPI contactless payments use near-field communication (NFC) or radio-frequency identification (RFID) embedded in a card’s microchip. When you hold the card or device close to a point-of-sale terminal displaying the contactless symbol—similar to a Wi-Fi icon—the terminal and card exchange encrypted data.
The terminal confirms the communication with an audible beep or light. The payment information is sent to the bank for authorization, and if approved, the transaction completes within seconds.
How to Set It Up on a Smartphone
Setting up contactless payments on a smartphone is typically a one-time process that enables fast, secure tap-and-pay transactions. Steps vary slightly between banks and apps, but the general process is:
Step 1: Log in to your official net banking portal or mobile banking app.
Step 2: Locate the option for “tap and pay” or “contactless payments.”
Step 3: Enable the feature and follow any on-screen verification steps.
Step 4: Set the chosen card or payment method as the default for contactless payments.
Once enabled, you can use your phone to tap and pay wherever contactless NFC payments are supported. Many payment apps also let you add cards and manage settings from within the app.
Choosing a Contactless-Friendly Card
If you want a card that integrates smoothly with smartphone and UPI payments, consider cards designed for mobile-first use. Some modern cards link directly to UPI IDs or mobile wallets and offer added benefits such as cashback, lounge access, and fee waivers. Evaluate fees, rewards and security features when choosing a card that fits your needs.
FAQs on Contactless Payments
Are there limits to contactless payment transactions?
Yes. Currently contactless payments without a PIN are limited to ₹5,000 per transaction. For amounts above that, a PIN or additional authentication is typically required.
What should I do if a contactless payment fails?
If a contactless payment fails, try retrying the tap or use an alternative method such as a UPI app linked to your bank. If problems persist, contact your card issuer or bank to check for issues with the card or account.
How do I deactivate contactless payments on my card?
You can usually deactivate contactless functionality through your bank’s online banking portal or mobile app, or by contacting customer support to request the change.
Can I use my contactless payment card with a damaged chip?
No. If the card’s chip or NFC antenna is damaged, contactless transactions may not work. In that case, request a replacement card from your bank.
