[周刊王CTWANT] With the official launch of the iPhone 15 series, in addition to new features such as action buttons that have begun to be studied by many users, some unknown secrets in the iPhone 15 series have also been exposed to the sun. It is currently reported that there is actually a QR Code hidden on the outer packaging of the iPhone 15 series mobile phones that can be identified using ultraviolet light. On each screen, there is also a QR Code that is almost invisible to the naked eye. You must use it. Only professional instruments can be used to read it.
In fact, as early as when the iPhone 14 was launched, Apple officials used packaging seals to ensure that the phone was brand new and unopened. However, it was immediately imitated by counterfeiters, who made fake seals to match the new phone, pretending to be a brand new phone and selling it to the outside world. for sale. Therefore, Apple did not specifically promote anti-counterfeiting at the new phone launch event this time.
After the product was officially launched, local stores in China used UV light to illuminate it. As a result, in addition to the anti-counterfeiting label, a small QR Code was seen on the outer packaging of the mobile phone. As long as consumers or stores scan this QR Code, they can know whether the iPhone 15 in their hands is truly brand new and original without opening the package.

In addition to the QR Code on the outer packaging, there is also a QR Code on the screen. According to a report by “The Information”, the QR Code hidden on the iPhone screen is only the size of gravel and is carved on the glass of the screen. In addition to its anti-counterfeiting effect, it is also used by Apple officials to track product quality. Through this QR Code, officials can confirm how much screen glass the manufacturer has produced, and also how much screen glass is discarded in the process.
Also because these QR Codes are very small, only about the size of gravel, professional instruments must be used to read them. Apple developed this technology to improve the yield rate of its products. In the past, foundries had prevented Apple from understanding the defect rate of its products, so Apple used this move to compete with them. But the actual effect is also very obvious. After the introduction of this technology, the yield rate of screen glass alone has increased from the original 70% to 90%, helping Apple save hundreds of millions of dollars in production costs every year.
The report also mentioned that this technology has actually been introduced since 2020. It is not only found on the screen glass, but also on many internal parts. These QR Codes that cannot be observed with the naked eye are also present.
