Mobile payments are becoming a good alternative to pay in different stores and shops that are compatible with these, and that is, after all, the most convenient way to pay, simply remove the terminal, unlock it and put it next to the dataphone.
That they are comfortable is more than clear, however, it seems that these may not be as safe as they seem, since they have certain vulnerabilities that can cause our data to be stolen, and that other people use the cards we have stored in services such as Android Pay, can you imagine how?
Paying with your mobile phone seems extremely comfortable, although, if I’m honest, I’ll always prefer to pay with cash, except for essential cases, or for situations in which I’m in a hurry, among other things, because, at last, And finally, a charge to your card indicates where you have been, and turning this into a habit makes it possible to know where you are at almost all times. Paranoias, yes.
And the truth is that, beyond this, it seems that mobile payments may be less secure than they appear, as explained by Professor Zhe Zhou of Fudan University (China) in The Register. And, he gave a talk recently talking about the subject, which is quite enlightening.
In it the professor explained a little the functioning of these mobile payments, which, in case you did not know, work the same. When you enter your card in the application, an identification number is generated, called a token, which is then transferred to the bank along with the charge to be made to our account.

Well, according to the professor, each transaction uses a single token that can only be used once, and therefore, the only way to be able to use another person’s fraudulently is to prevent it from reaching the payment server. And there are smartphones with secure magnetic transmission that can do this, emitting electromagnetic energy through the coil of wireless charging.
Something that can be carried out at a distance of around seven centimeters if we talk about smartphones, but that, with a special device, can be done from a distance of up to seven meters. And this illustrates quite well that, although it is a relatively safe payment mechanism, there is always some vulnerability to face.
