Now the startup is working to expand upon that earlier prototype with a card that’s now integrated with both Coinbase and Ripple accounts, letting pilot testers pay for goods and services via their existing virtual currencies accounts. The plan is to also integrate the Shift payment card with loyalty points programs and regular bank accounts in the future. The payments between fiat currencies, digital currencies, mobile minutes, loyalty miles, and more will happen using Ripple as a settlement protocol. With an accompanying mobile app, users can switch their funding sources on the fly, and track their transactions. The card works offline, online, and internationally, thanks to the support of a major international card network.
