I don't like this direction at all, but people like big screens (that crack easy).

Makes you wonder if the cost and weight of a more durable screen on a device like this matters as much as on a phone.

If you have a lot of funds stored on the wallet secured by it, IMO your hardware wallet should be locked in your desk / safe / wherever and pulled out when you need to move them. And you have the seed backed up securely someplace else anyway.

If you have smaller amounts, then getting the screen broken is an annoyance since you do have it out and use it day to day, but the seed it still elsewhere.



Additionally, I think I found the QR scanner part they are using. This means the QR scanner is essentially a standalone black box computer running proprietary code. It also means that there will be no viewfinder on the Q1 screen: https://www.alibaba.com/product-detail/Embedded-1D-2D-Image-Barcode-Scanner_62478427468.html?spm=a2700.galleryofferlist.normal_offer.d_title.2e971000ZaPAEz&s=p

Does anyone make their own camera modules? There was actually a discussion here a while ago about that and vulnerabilities with them.

In their defense again, secure element you are using in Passport is also not open source and it has security issues, that is why it was outdated by manufacturer Wink

What a lot more wallets need, and other then the keystone I don't know of any, is a 'self destruct' when taken apart so you can't attack them by taking them apart and getting to the SE. BUT the other side of that is you can't take them apart to fix them either.
