Security is the major concern when it comes to possession of a credit card. The recent news states that users can take advantage of a fingerprint sensor feature in order to increase its security and privacy. Mastercard has been conducting some trials regarding such technology, especially in South Africa. Two of those trials were successful! So, how does the system work? As the name suggests, users should have confirmed their fingerprint when buying something. What they need to do is to put their finger on the sensor.


Understanding the Fingerprint Sensor Feature

The purpose is to improve both security and convenience when using a credit card. It is because bad people would face troubles when trying to replicate it. Does it mean such technology has no weakness? Well, some professionals are able to gather information of a card user’s fingerprint from things people have touched back then. It is true card holders can change their date using their other fingers. Yet, they only have 10 fingers. Once they run out of options, bad people can easily steal their data.

Despite such weakness, many experts have approved the efficacy of credit cards’ fingerprint sensor feature. For instance, they are able to avoid hassles like bad passwords. With the presence of the sensor system, there is no need of a scanner. That means it has better functions than preceding biometric payment cards, which has a limit in usability. The reason is the previous system can only work with the right equipment. No wonder, card holders often find difficulties when they are going to purchase products, as they need to find stores providing the right machine.


Safer and more Convenient Credit Cards

In the last year, Mastercard also had introduced facial-recognition software and fingerprint authorization. The good news is the development or improvement is still being made. According to Mastercard, their feature works with any EMV terminals. Not to mention retailers don’t need to undergo difficulties like installing new software or hardware. For card holders, they only need to register the card and their fingerprint. Later, the bank converts such unique fingerprint into a digital password. Even though it is not a perfect system, it has better security and efficacy, as compared to previous technology.

When purchasing a product, they can simply put their finger on the card’s sensor. That’s all. Not only it is efficient, but such feature is quite safe. In fact, more developments are being made. This includes the contactless version of fingerprint credit cards. As mentioned before, there have been some trials in order to find out the efficacy of such technology. Mastercard did it in South Africa, both in a supermarket and a bank. Both of them were satisfactory!

In summary, Mastercard’s fingerprint sensor would be a big help for banks, stores, and card holders. It increases both security and convenience of a transaction. The risk is indeed available, but it won’t as scary as before. Replication is possible, but it takes lots of efforts to do so. With such minimum risk and excellent benefits, people are likely to use such technology in the near future.
