Cold Wallet and Payment SuperCard
GRAFT cold wallet / payment card allows the same instant payment at the point-of-sale, but without the mobile phone app. Cold wallets are also safer for private key storage as they are not subject to malware on mobile phones.
* The ColdPay card is being developed in parthership with an innovative smart card manufacturer.
GRAFT is not planning (as of this time) to be in the card/wallet business. We’re partnering with a card manufacturer to build this as a reference card. This doesn’t preclude others from doing the same – in fact we would encourage that.
The battery in the ColdPay card is rechargeable with USB charger and lasts approximately 2.5 hours of continuous operation on a single charge.
