Is It Safe to Save Credit Card Details on Apps?

Almost every shopping, food delivery, travel, and entertainment app today asks users whether they want to save their credit card details for faster checkout next time. The convenience is undeniable, but the question of safety is one that most cardholders silently struggle with. The reassuring news is that the regulatory framework in India around card storage on merchant apps has been strengthened significantly, and cardholders now enjoy more protection than ever. Understanding how this works helps you make confident, informed decisions about which apps to trust with your card details.

The Old Way of Storing Card Details

Until a few years ago, many merchant apps stored the full sixteen digit card number, expiry date, and cardholder name in their own systems for the convenience of one click checkout. While this was useful, it concentrated sensitive card data across hundreds of merchant servers, which became a tempting target for data breaches. A leak at any one merchant could expose the same card number across multiple platforms.

The Shift to Tokenisation

The Reserve Bank of India introduced card on file tokenisation rules to address this risk. Under the new framework, merchants and aggregators are no longer permitted to store the actual card number, expiry, and CVV. Instead, when a cardholder agrees to save the card on a merchant app, the card network and issuing bank generate a unique token, a randomised reference value, that is specific to that merchant. The merchant stores only the token, not the real card number.

Why Tokenisation Matters

Tokens are useless outside the merchant for which they were created. Even if a token is leaked through a data breach, it cannot be used to make purchases on a different app or website. This dramatically reduces the impact of a security incident at any single merchant. Tokenisation also limits the surface area where the actual card number lives, restricting it to the issuing bank and the card network.

What Apps Are Allowed to Store

Under the current rules, merchants and aggregators are typically allowed to store only the last few digits of the card number and the cardholder name for display purposes, along with the token. This is enough for the user to recognise which card is saved, while keeping the full card number out of the merchant's reach. The CVV is never stored and must be entered for each transaction unless an alternate authentication method is used.

OTP and Two Factor Authentication Still Apply

Even on a saved card token, transactions in India typically still require two factor authentication for the cardholder, usually through a one time password sent to the registered mobile number. This means a stolen device or compromised app account alone is unlikely to result in unauthorised transactions, since the OTP adds an extra layer of protection.

Where Real Risks Still Exist

Despite the regulatory protections, certain risks remain. Phishing apps that mimic legitimate ones can trick users into entering card details directly into a malicious interface. Reused passwords across apps can let attackers log in to a saved card account if one platform is breached. Social engineering, such as fake customer care calls asking for OTPs, continues to be the most common cause of fraud, far outpacing technical breaches.

Choosing Which Apps to Trust

Save card details only on apps that are well known, downloaded from your phone's official app store, and operated by recognised, regulated merchants or licensed aggregators. Avoid saving cards on small, untested platforms, especially those promising unrealistic discounts. The fewer the apps that hold even a token of your card, the smaller your overall risk surface.

Practical Steps for Safer App Use

Use strong, unique passwords for accounts with saved cards, and enable two factor authentication wherever the app supports it. Lock your phone with a strong PIN or biometric authentication so that someone with physical access cannot easily make purchases. Review the list of saved cards inside each app every few months, and remove cards that you no longer use on that platform.

What to Do If a Card Is Compromised

If you suspect that a card has been compromised through any source, contact the issuing bank's customer care immediately to block the card. Request a reissue, dispute any unauthorised transactions, and review your credit report a few weeks later. After a card is reissued, your stored tokens on merchant apps stop working, since they were tied to the old card, and you can decide which apps to re tokenise with the new card.

Saving Cards on Bank or Wallet Apps

Saving cards on the issuing bank's own app or a regulated wallet is generally safer than saving on merchant apps, since these entities operate under strict banking regulations and security audits. The bank's app already has access to the card details for billing and statement purposes, so adding them for payment use does not significantly increase exposure.
