As digital payment apps like Google Pay, Apple Pay, and others continue to rise, making everyday purchases has never been easier. Rather than lugging around a wallet full of plastic card, now all that is necessary is to use your smartphone or smartwatch at retail shops and transit stations. The questions left--is this really secure to use payment apps?
In this detailed guide, we look at the security features of payment apps, how they work, if they are secure for both online and offline payments, and if you should use them for your everyday transactions.
The Shift to Digital Wallets
Digital wallets have revolutionized the way we deal with money. Gone are the days when one has to carry cash or physical credit cards. Today, apps such as Google Pay, Apple Pay, Samsung Wallet, Paytm, and PhonePe allow users to pay effortless through smartphones and smartwatches. This has reduced dependence on physical wallets and also simplified access to services like public transport.
But with that increasing popularity, there's bound to be some question about security. Is your payment information vulnerable to someone swiping? Are you at risk of fraud if you should lose your phone? Let's dig a little deeper into how these apps work and assess what security comes with them.
How Payment Apps Like Google Pay and Apple Pay Work
Google Pay and Apple Pay are contactless payment applications based on near-field communication (NFC) technology. NFC is the data transfer that occurs wirelessly when two devices (such as a phone and the payment terminal) are brought into very close range. If you have ever used a hotel key card or an office keycard, you have already come in contact with a form of NFC technology.
When using these apps, the credit and debit card information are not stored on your phone because they are not sent to the app. However, they become tokenized in order to help with security.
What is Tokenization?
Tokenization substitutes sensitive information used to identify a payment card-for example, a typical 16-digit card number and its expiry identification-with a unique, randomly-generated number called the token, which is transmitted to the bank or card issuer, where it is linked to the actual card, and used in place of the actual card number at the time of payment.
Online firings are characterized by the fact that no two transactions could ever use the same token, meaning that since the token is valid only once, intercepting the transaction will hold little value to a hacker as it will not be valid for any further action. Thus, there is equal assurance that information about your real card is never exposed. Hence, payment apps are safer than using a physical card.
Are Payment Apps More Secure Than Physical Cards?
Yes, apps like Google Pay and Apple Pay are actually more secure than carrying around physical credit or debit cards. Here’s why:
Tokenization: As mentioned above, payment apps use tokenization, which means your actual card details are never transmitted during a transaction. This reduces the risk of fraud significantly compared to physical cards, where your card number can be stolen through card skimming.
Biometric Authentication: Before you make a transaction, a pop-up will normally ask you to verify the transaction through biometrics, for example, fingerprint or facial identification or through a PIN. So even if someone steals your phone, you will still be safe because they won't be able to access your stored cards without completing that verification step.
One-Time Use Tokens: Tokens change with every transaction, meaning that even if someone were to intercept the token, they would not be able to reuse it.
No Skimming: Scammers often use skimmers to steal card information when you swipe a card. Because Google Pay, Apple Pay, or other apps rely on NFC and tokenization, there is no physical card to swipe, so any risk of skimming is totally diminished.
Can Anyone Use Saved Cards If You Lose Your Phone?
The card details you save in Google Pay, Apple Pay, and other such applications are secured with different layers of protection including the lock screen password of your mobile device or biometrics. Even if in the worst-case scenario your phone happens to be stolen, a thief won't be able to use your cards without unlocking it first.
Wearable Devices and Payment Security
Even on the likes of an Apple Watch, the payment apps still require you to enter a PIN before proceeding with a purchase. These measures provide an additional layer of security, ensuring that only you can use the cards stored on your phone or smartwatch. These safeguards make it all the more safe to lose the phone with already-installed payment apps than it is to lose a wallet with several cards inside.
The Safety of Tap-to-Pay in Public Places
A major concern that users have is within the area of tap-to-pay apps, whether at retail outlets or public transport systems their card details might be stolen while making electronic transactions. Tokenization gives users the confidence that actual card details are never transmitted during a transaction.
Again, let's suppose someone intercepted your payment: he could only get the token that cannot be reused. In other words, pay through many tap-to-pay apps, like GPay or ApplePay, it is usually much safer than by swiping the plastic card.
Apple Pay and Google Pay for Online Purchases
Online and in-app payments through Apple Pay and Google Pay have the same security as those done at the point of sale. You do not have to enter credit/debit card details on your phone when you are shopping online or through an app. In fact, the app is creating a token just like it will do for the transaction at the point of sale.
That means that the website or app from which you are making the purchase never actually sees your actual card details. Of course if the merchant's systems get hacked, then your payment data is safe, since this is in recent years when data breaches have emerged as a growing concern.
UPI-Based Payment Apps
In India, UPI (Unified Payments Interface) has become the dominant method for making payments, with apps like PhonePe and Paytm leading the charge. But is UPI safe to use?
Yes, PhonePe and Paytm are both considered safe for UPI transactions. Here’s why:
Two-Factor Authentication: UPI transactions typically require two layers of authentication: your UPI PIN and an OTP (one-time password) sent to your phone.
Secure Encryption: UPI-based apps encrypt all transaction data, ensuring that your payment details are safe from hackers.
However, it's essential to remember not to share your UPI PIN or OTP with anyone, as doing so can give scammers access to your account.
Is PayPal Safe to Use?
PayPal is one of the most widely used digital payment platforms globally. It is considered safe because:
Fraud Protection: PayPal offers buyers fraud protection, ensuring that you can dispute unauthorized transactions.
Encrypted Payments: Like other payment apps, PayPal encrypts all transaction data to keep your information safe.
Two-Factor Authentication: PayPal also supports two-factor authentication, adding an extra layer of security to your account.
As more users are using UPI Apps like PhonePe, PayTM, and Google Pay, the scams that victimized users are also increasing. In my blog "Exposed: The Rise of PhonePe Scams and How to Stay Safe in the Digital Payment Landscape" these are the newest schemes used by fraudsters to take advantage of the vulnerability of a digital payment system. From phishing attacks to spoofed UPI payment links, I run you through all kinds of scams, how they work, and-most importantly-share actionable tips on how you can keep your hard-earned money and personal information safe while using PhonePe or other UPI Apps. So go on, remain aware, and remain safe in today's digital world!
In conclusion, Google Pay, Apple Pay, PhonePe, Paytm, and PayPal are widely regarded as safe choices for everyday payments as they offer a greater degree of security as compared to plastic cards through tokenization, user biometrics, and secure encryption. Although no system can provide complete protection from fraud, these apps at least give you substantial blocking against prying eyes into your financial whereabouts.
To secure your transactions as much as possible, always use strong passwords, enable biometric controls, and never share UPI PINs or OTPs with anyone. With these tips, payment apps can be used with the utmost confidence for your transactions with your essential purchase information safe and secured.
