Protean Payment icon
Protean is creating the next generation payment card: Echo. Echo replaces all of your other cards (e.g. debit, credit, loyalty) and makes payment more convenient and secure. It communicates via Bluetooth with a mobile wallet app and instantly replicates any of one of your cards’ magnetic stripes. Simply, select a card on the mobile app, and Echo swipes as though it were that card.
