Samsung unveils its biometric credit card, safer and more practical

Samsung has developed a new circuit board that promises to make biometric cards more secure and more ergonomic.

On January 25, Samsung Electronics presented its latest innovation: a biometric credit card that embeds a fingerprint reader. But above all, it is coupled with two security modules to secure transactions.

Of course, this is not the world’s first biometric card. This is a concept that is not very common yet; but it is nevertheless beginning to appear on the market, for example at BNP Paribas. These cards work exactly as one would expect. When checking out, all you have to do is present your card in front of the terminal while placing your finger on the fingerprint reader.

What differentiates Samsung’s proposal is the presence of additional security elements integrated into a single chip. In addition to the fingerprint reader, there is actually what Samsung designates as a “secure element”. It is in fact a kind of digital “safe” to protect the fingerprint against unauthorized access attempts. Finally, the last element is a “security processor”. Samsung explains that it serves to “extract and analyze the unique characteristics of the fingerprint placed on the sensor”.

In particular, he will have the heavy burden of determining whether it is really the owner’s imprint and not an imitation. Samsung claims that its proprietary technology “prevents unauthorized users from circumventing the security system with illegitimate methods such as artificial fingerprints”. As it stands, it remains very difficult to judge the real effectiveness of this countermeasure. But it is still reassuring that the manufacturer alludes to it.

Towards a new generation of universal biometric badges?

Samsung explains that this new printed circuit will make it possible to develop a new generation of biometric cards. These will gradually become more secure, but also faster and more ergonomic to use. And it’s not just about payment. According to the manufacturer, it is a technology that would also be versatile and suitable for many other situations. We can also imagine using it as identification cards for students, as a badge for an employee, or even as a personalized key to access a building.

Eventually, we can even imagine a world where each person will have only one card of this kind. It would then make it possible to manage identification, payments, as well as the various physical accesses available to the person. Practical in appearance, but also all the more disabling in the event of loss…
