Status, an Ethereum messaging app and a mobile browser startup, has recently relaunched a cryptocurrency hardware wallet called Keycard, that’s set to be sold for only $29 on its website. It’s shaped like a regular credit card, and lets users sign transactions with a “tap-to-pay” feature.

Speaking to CoinDesk Status’ project lead Guy-Louis Grau noted that the wallet has the “exact same shape” as the Visa cards people currently use, and added that the Keycard is contactless and will work as a mobile crypto wallet. Grau was quoted as saying:

[Keycard] is contactless. It’s going to work with your mobile crypto wallet. You’ll just need to tap your Keycard on a mobile device to sign transactions. Functionally speaking, it’s really a hardware wallet but it works with mobile.

Per the report, the cryptocurrency hardware wallet is compatible with various cryptocurrencies, including bitcoin, bitcoin cash, ether and ERC-20 tokens, XRP, and litecoin. The first batch of Keycards is “expected to arrive in the mail to interested parties by early March.”

Initially, these won’t be user-facing, as Grau noted Status isn’t announcing a “full end customer product” with it, but noted it’s “releasing a tool” for “third-party blockchain projects that want to secure their application with a cost effective hardware wallet.”

Keycard’s integration into Status for end-users, Grau notes, will be released later on this year. Unlike other cryptocurrency wallet manufacturers, Status is reputedly looking to encourage people to build the card themselves.

To boost security, it uses technology that’s been around for a while, and is open-source as the security of a cryptocurrency wallet is “tightly linked with openness.” Grau noted that software and hardware being open-source is the “most important thing.”
