SD card PSBT management is not as secure as QR.

To make it the same security you would need to use a new SD card for every signed transaction.

So what did they do?! They worked on the MK4 with NFC.

NFC isn't as secure, nor is it as useful as QR signing.

Another benefit of QR based HWWs is address verifications, which you can do much easier.

They tried to hit the marketing channels with security fud first & foremost.

Then, they tried an alternative to claim superiority.

Then, they joined us.
