We may actually have to lick cartridges to verify their authenticity.
This has happened with the DS, 3DS, and now, seemingly, the Nintendo Switch and Nintendo Switch 2. For years, Nintendo games have been major piracy targets due to rising costs, with Nintendo actively combating this by going after creators of emulators and ROMs to either obtain games illegally or simply preserve them.
As discovered by the mods of r/gameverifying, cartridges for both the original Nintendo Switch and the Nintendo Switch 2 can now be recased, enabling the creation of counterfeit cartridges that could be passed off as authentic copies.
The reproduction casings are reportedly offered in two versions: the chip and the PCB. The chip version consists mainly of the core component with copper contacts on its back, while the PCB version includes the entire full-sized printed circuit board. Most importantly, these casings are injection-molded rather than made using 3D printing methods, which have been around for a while.
Here are the legitimate rear casings for the Switch and Switch 2 chip variants:

Fortunately, there are several ways to tell fakes apart from originals, including differences in logos, identifiers, thickness, and, yes, the fact that originals have a bitter taste. The details on whether these reproductions are actually circulating are still unclear, so take this information with a grain of salt.
