Contactless payments using smartphones are gaining recognition for their improved security compared to traditional credit cards, according to recent reports. Although contactless payments—also known as NFC (Near Field Communication)—are now common in daily life, whether through a physical card or a smartphone, the mobile option still faces some resistance from users. Despite this, it offers clear benefits over the traditional plastic card. Some people still prefer to disable NFC on their phones and opt for the more familiar method of inserting their card and entering a PIN. However, even with more secure technologies, it's always possible for highly skilled hackers to bypass these systems, including NFC, and access sensitive financial information. Using a smartphone for payments can appear to come with more constraints than using a physical card. It requires a modern, compatible device that is up to date, as well as entering credit card information into a specific app, such as Google Wallet, Samsung Wallet, or Apple Wallet. This process can give more personal data to large technology companies. Additionally, it may feel redundant compared to using a physical card, and many people are hesitant to centralize all their financial activities on a single device. If a phone is lost or stolen—often containing credit cards and personal identification—it can create serious problems. However, this risk is not unique to smartphones, as a lost physical wallet also poses similar threats, and both situations can be problematic if the device or wallet is compromised or the phone’s battery dies. Losing or having a credit card stolen presents a real risk to a person’s bank account, especially since the card is not protected by the biometric security or lock pattern of a smartphone. If a thief cannot withdraw money from an ATM without a PIN, they can still make contactless purchases (if enabled) and perform online transactions using the information printed on the back of the card. This is a vulnerability that the smartphone version of payment does not face. During a contactless payment, a credit card transmits its number to the terminal, which theoretically could be intercepted or stored. In contrast, a smartphone payment generates a unique encrypted token for each transaction, which is useless to anyone trying to misuse it. Another key security advantage of smartphone payments is the requirement for user authentication before completing a transaction. This is usually done through biometric methods like fingerprint or facial recognition. As a result, someone who finds your phone cannot make payments without your permission, unlike with a traditional credit card. Additionally, while the instant and passive nature of physical cards still has its supporters, the smartphone version allows for larger payments, as it is not limited by the lower contactless payment threshold of €50 for cards. Instead, smartphone payments are limited only by the weekly or monthly limits set by the bank. Thanks to better security and the systematic verification of the user, contactless payments via smartphone offer greater flexibility and safety.
