Well, this spells nothing good for other expensive hardware wallets, like Ledger and Trezor. 
On their website it shows something that says, "Remaining Signatures : 999" ....so they have a limited use.
The $20 per card is still cheaper than most of the hardware wallets out there, but very expensive for people in 3rd world countries.

The $20 is for the special limited edition set. It says "Fully reusable, unlimited times". So that is good value compared to Ledger and Trezor even as a one coin wallet.
Like I said if the limited use ones end up being a few cents each then that'll really work as a banknote substitute.
