Safety Tales: QR Code for Dinner
Vladimir Bezmaly | 02.08.2021
Mark had booked a table for the evening at his favorite restaurant, Old Sam's. He was going to go there with the beautiful Anna, with whom he had recently started working in the same lab.

Evening gradually came.

- Hi, Anna! Let me remind you!

- I remember. At 8:00 PM "Old Sam's". I won't miss such an invitation. They say there's a new menu.

— We'll come and see.

Here it is evening. Mark arrived 10 minutes early.

- Good evening! Here is our new menu.


— You scan it and then choose what you would like from our online menu. The kitchen immediately knows which table this or that dish is ordered for. You win in terms of service speed.

- Yes, thank you! I know about such service. But please invite your administrator. I have a number of questions for him. Don't worry, it's not about your service.

Mark, out of habit, automatically checked whether the restaurant's logo was on the QR code and whether the QR was different from the neighboring tables. After all, an attack on a QR code substitution is easy to carry out by simply re-sticking the code.

A minute later the administrator appeared at the table.

— Do your QR codes collect personal finland mobile database about customers, such as order details, phone number and emails?

— We don’t hide it. This is necessary so that restaurants and cafes can analyze people’s behavior and create a profile of them. Databases created on the basis of the information received can be used for marketing campaigns, such as personalized discounts or recommendations.

— Have you ever thought that such implementation of QR codes could threaten the privacy rights of cafe and restaurant visitors? After all, anything can be programmed into a QR code — from collecting current location data to permission to make a call or even a payment transaction. After all, the main problem with reading a QR code with most scanners is that the link is followed automatically, without asking for permission to perform additional actions.
