What can they know when paying with the NFC of your mobile

Mobile devices are becoming more and more essential tools over time. And all thanks to the fact that different manufacturers are adding essential functions and characteristics. As is the case of having an NFC chip in smartphones . With this component we will get to perform different tasks with our terminal in a faster way, including being able to make payments.

However, there are not all the people who trust the security of this tool that allows us to make payments at the moment without having to resort to our physical bank card. More than anything, because they fear that their card details will be stolen and may even suffer fraud. However, with today’s technology, mobile payment has become a more secure option.

What can they know when paying with the NFC

Can they steal data when paying with the mobile?

As we said, carrying out the payment with our mobile device has become the safest method, even more so than using the traditional credit or debit card. This is because, basically, when paying at a local with our terminal certain codes are shared that are unique and random that have a single use, better known as ‘ tokens ‘.

In addition, once it is created, it will be the one that identifies the operation that we are going to carry out. In this way, when making a purchase in any type of establishment, the number will not be stored or on any external server. Although in the case of iPhones, when using Apple Pay, a unique fully encrypted device number is used.

Even in the case of smartphones with the Google operating system, it has added a function from Android 10 that allows them to enable the use of Secure NFC . That is, the chip will only be activated if the smartphone screen is fully unlocked. In this way, you will not be able to make payments. To enable this option, use the internal search engine of your smartphone.

In the case of iPhones, it will only let you send your payment information when your smartphone manages to authenticate you using Face ID , Touch ID or the security code you set to unlock your Apple smartphone. So these ways are the security measures that are used in the different smartphones so that the transaction is totally safe.

The mobile’s NFC uses a short-range frequency , so it will also be necessary to bring the smartphone closer than 10 centimeters from the POS. Even if fraud is suffered, we will have the same legal coverage that traditional credit or debit cards provide.

Who has information about your transactions

Of course, Google Pay or, also in the case of this Apple service, although there are many others, none of them transmit the information and do not issue it to third parties. In addition, our bank details are not shared with the merchant with which we have purchased. So the only one to know our bank movements will be us and our bank. Well, from the app of our bank we can know what kind of information they know :

  • The exact date and time an operation was performed.
  • In which establishment we have made a transaction.
  • The amount we have spent.

Although, it must be borne in mind that, having a bank application, when using it, it will request a series of permissions such as our agenda to be able to facilitate payments to our contacts or the location, although in this case we can restrict this access, already Depending on the application itself, it will serve a specific function such as locating nearby ATMs or offices through the app. So you should carefully review the permissions that you have granted and which ones are dispensable. In addition, they have SSL or TLS security protocols so that our data cannot be easily decrypted when logging in and a secure connection is made.

However, you have to know that if you use third-party apps, such as Fintonic , to more accurately track your expenses, you have to know that they will have access to your account password. And, in addition, it requires permissions such as our location or phone number. In your favor we find that you will not expose our information to third companies either, since our personal data that we give you is protected under the General Data Protection Regulation.
