Wouldn't be too much work for you to extend a bit more your research by adding the description of GUI used by different HWs to enter PIN code?. Recently the firmware of ledger nano s+ has been elevated to 1.0.4 and the most noticeable change was the new GUI to enter PIN code. I think the new GUI in s+ is more convenient than it was before upgrade.
Hi satscraper.
I really don't have time to do this for all hardware wallets and I don't personally own all devices to know about this, but people can write about that in this and I will consider updating something.
My idea was to collect basic information how PIN code function in this devices, that is not related with GUI on specific devices that can change all the time.
I think that wallets like Passport, Colcard and maybe Keystone have one of the best GUI's for entering PIN codes and it's much easier to enter PIN when you have numbers and real buttons.
Thanks for your response. I have managed to find the relevant answer from
reliable source. They had to modify PIN interface to elevate the level of security: "We hence decided to design a whole new PIN-entry interface, conceived specifically to prevent any meaningful dependency. From a security standpoint, the philosophy of this design is simple: instead of trying to hide the number of illuminated pixels in each row, we will make this information useless to an attacker, by making it independent of the typed PIN. The straightforward way is to make the number of illuminated pixels in each row constant."
