Count card wallets as hardware wallets...?
Card wallets (like useburner and tangem) are going to score poorly if marked as hardware wallets, because categorically they do not have interfaces to display transaction data.
Should we have them be their own category? Or slot them in with hardware wallets?
It's a good question. I think it may make sense to have them as a separate category; perhaps we can call them "hardware keys" rather than "hardware wallets". The use of the word "key" reflects that their only job is to sign things, and that they are only a component of a larger whole (which is the actual "wallet").
Another potential solution is to treat them as hardware wallet, but with some special bit in the feature data that states they have no display. Then the attributes that don't make sense to enforce on display-less devices would need to be updated to return the EXEMPT rating if this bit is set.
