Why does Apple put a secret barcode on the iPhone screen?

From iPhoneIslam.com, a phone displaying a text message on its screen.

Since 2020 until now, Apple has placed two quick response codes (QR Code) on the iPhone screen, but what is the benefit of these codes for the company? The answer is that they help save a lot of money for Apple.

This bar code cannot be seen with the naked eye

The story began when Apple felt that its suppliers (Lens Technology and Bell Crystal) were deceiving it by hiding the real number of defective screens that were manufactured for the American company, and thus the iPhone maker incurs additional costs in exchange for producing a large number of screens for its iPhone devices, and this is why Apple decided Spending millions of dollars to add two barcodes to each iPhone to track how many units of the glass cover were produced by its suppliers.

According to the “The Information” website report, Apple has been using barcodes in iPhone devices for approximately 4 years, and the location of the QR codes has changed over time. For example, in the iPhone 12, the barcode was located above the front speaker, while in the models. Newer, the icons are located next to the bezel at the bottom edge of the screen.


Screen barcode development

The report also indicates that the process of developing this type of barcode was very difficult for Apple. Initially, the codes were laser-etched into the glass, but this eventually weakened the iPhone's screen and in drop tests, cracks in the glass often came from where the QR code was placed.

That's why Apple engineers had to invent new technologies using microscopic lenses with ring lights, and the result turned out to be positive. Since introducing these symbols (one is the size of a grain of sand and can only be seen using special tools, while the other is about the size of a pen tip), Apple suppliers have reduced the number of defective glass units to 10 in 3, compared to 10 in XNUMX. Previously cut.

 Finally, Apple's keen attention to detail in manufacturing devices such as the iPhone is what drives it to search for any solutions to its problems. That's why it was able to reduce defective screens and prevent its suppliers from stealing them; Which helped her reduce the costs she incurred every year.

After discovering this secret code, is it possible for it to be exploited for things that harm the user’s privacy, such as identifying a specific person’s device and linking it to this code, since there is nothing that distinguishes the iPhone from the outside? Tell us in the comments
