Wow, these look absolutely awesome. I've known Tibu's products for a while, but never got one since I strongly advocate for hardware wallets with a display.
There is a way to have display with Satochip card format hardware wallet, but it won't be so cheap anymore.
I will write more about that soon in a different topic, so for now only decent alternative is maybe CoolWallet.
Another way to sort of have external screen for address/transaction confirmation is by using open source Satochip 2FA mobile app, it works good.
That way you are not going to have blind signing anymore with satochip.
do you know whether it is possible to use a phone as NFC reader? A lot of smartphones nowadays have this functionality built-in, meanwhile laptops don't. It would be perfect if there was something like an open-source companion app that connects to Sparrow and lets someone use their phone as a reader.
I think that NFC reader on your phone should work fine, but to be sure better contact Satochip support for confirmation.
Pro tip: You can easily get cheap but good old Thinkpad laptops that already have integrated chip readers
