    I think they should instead just introduce a clear system for verifying that a Raspberry Pi is genuine. For example, a code printed directly on the device. If you enter that code on the website, you can see exactly which model it belongs to and how often it has been used. That way, you could determine whether a Raspberry Pi is new or used and whether it has been modified. I saw that once at a thermal paste manufacturer. They used it to solve the problem of counterfeit thermal paste.You just have to get people to actually use the system and tell anyone else who asks for support but doesn't have an original copy to GTFO.This would allow them to avoid the increased support burden without limiting people's ability to upgrade their Raspberry Pi.

      Chinese scammers have gotten good at abusing those "codes" by having a list of "known good" codes and printing them on multiple units. And because those holographic codes some companies used are printed in China, the scammers just use the same equipment during the night shift.

        There are methods of doing so that identify multiple, harder to falsify things.

        One that I have seen is HMAC(serial||SKU) as a datamatrix&#x2F;QR, laser-etched onto the top silkscreen and burned into a PROM.

        Just show everyone who looks up the code how often the code has already been checked. If you get a new product but the code has been checked 628 times, it’s probably a reused code.
