The Keycard team has also released an open API and SDK for Android, iOS, and Go. Developers can build Keycard functionality into any app requiring authorization or other user authentication.
When it comes to cryptocurrency security, it is literally all down to the private key used to access the account. One of the most secured options for storing private keys is using a hardware wallet.
Keycard uses NFC to allow transaction authorization by simply tapping the credit-card sized wallet against the mobile device. The keys meanwhile, remain safely stored on the device itself.
The Keycard is produced by the Status Network, who also developed the Status App, which it came integrated at launch.
The Status App combines:
- private messaging functionality
- an Ethereum wallet supporting ERC-20 and ERC-721 tokens
- a decentralized Web3 browser
The launch of the API and SDKs will allow the technology to be readily implemented in a host of wallets and other applications.
Whether it is to store private keys and authorize transactions, or as part of a two-factor authentication system.
Keycard project manager Guy-Louis Grau says:
“As a project with an open source API, we believe the Keycard model will be an industry standard for all sorts of products that expect normal people to interact directly with their cryptocurrency. Tapping a Keycard against your phone as an added layer of authorization and ownership of your private keys should be the norm anytime someone wants to login, send money, store value and more.”
Another benefit over the technologies employed by other wallet manufacturers to secure private keys is the price, as an NFC-enabled Keycard costs just $32.
