In a presentation at TechCrunch’s Disrupt NY 2015, startup Case demonstrated what it calls one of the most secure hardware bitcoin wallets, according to a report by TechCrunch. “There’s no easy and secure way to use bitcoin,” Case co-founder and CEO Melanie Shapiro said. “You’re either getting security, or you’re getting ease of use.” 
 
Case aims to provide both of these benefits in its bitcoin wallet. The small credit card-shaped device features a small screen, a fingerprint sensor, a camera, a built-in GSM chip and a few buttons.
 
To conduct a bitcoin transaction, users simply press the bitcoin button, scan the QR code using the camera, and swipe their fingerprint.
