Echo [$80-$100] is a Bluetooth credit card made of glass that syncs with its mobile app. Once a user has downloaded the app., they’ll plug in their card reader (dongle) and swipe all cards with a magnetic strip from their wallet (debit, credit, student ID, loyalty, etc.) into the app. The Echo card will then mimic any card that’s stored within the app. Echo consolidates all the plastic in your wallet to one, uber-card. Echo users won’t have to take their phone out each time they’d like to use a different card either, the Echo’s sleek design features three push buttons that correspond with the app. So there’s always immediate access to three cards at the push of a button – to switch cards in and out, simply drag and drop cards into the three spots from the app.!
