- I hope we come here again

- Why do you think they give me free coffee at Clara's?

- I think because you consult them. You are our cyber-policeman.

— That's right! After all, the main problem with a store's QR code is that it's practically impossible to tell it apart from an intruder's QR code by eye. Moreover, who's stopping an intruder from covering the static code with his own? No one!

- Is it that easy to create this code?

— Of course! After all, generator apps can be downloaded to your smartphone for free or found online. And while it may be difficult to find a moment in a large store when no one sees what’s happening at the checkout, it’s not that hard to wait until a street vendor is distracted or to replace a code in an automated point of sale.

- Wait, but as you were saying, there are also one-time QR codes?

- Yes! This is the payment method used in this cafe. But here we are.

- Good evening! What would you like?

- Two coffees and your amazing ice cream.

- Just a minute.

Alas, all good things come to an end. The ice cream is finished and the coffee is drunk. It's time to remember that tomorrow we have to go to work again.

- Thank you, Jean, the evening was amazing.


- Undoubtedly.

— The bill, please. I'll try to pay with a QR code. I'll egypt mobile database the code on my smartphone.

- Please, monsieur!

- Wait, something's strange. I received a notification about a withdrawal from my account, but for some reason the recipient was listed as a billiard room. Please, see your security.

- Do you have a problem?

- Yes. I'd like to review the video from your camera with you. And please don't let anyone out yet. This is a crime scene. Here's my badge.

- Oh, come on, sir, we already know that you are from the police. The town is small.

The video clarified the situation: the criminal standing behind the police officer simply photographed the QR code on the law enforcement officer's smartphone and immediately paid with it... himself. The cunning fraudster had registered the billiard room in his name in advance and installed an application on his smartphone that works as a QR scanner for business.
