NFC, without compromises
Introducing Portal: the hardware wallet for mobile users.
Details
The first mobile-native hardware wallet: designed to keep your keys safe and seamlessly integrate into any mobile & wallet app.
Portal leverages NFC technology, the same standard used by contactless credit cards, to safely and effectively connect with any modern smartphone. During signing the device will walk you through all the relevant parts of the transaction and allow you to confirm it by simply pressing a button.
Portal doesn’t need cables or batteries: it’s completely powered by the NFC.
