To verify the authenticity of the hardware wallet Ledger Nano S, we can recommend 2 ways:
1) Visual inspection of the packaging
As well as Apple products (do not count foradvertising), Ledger products have their own characteristics when packing devices: there are small holes on the packed film - evidence that the hardware wallet was sealed at the factory.
2) Internal inspection of device components
Earlier we described the main components of hardwarewallet, so do not be lazy and carefully inspect the insides. The presence of original parts, as well as the absence of excess elements indicates that the device is original.

For instructions on verifying product authenticity using Python, see the following article.
