KardiaMobile Card Provides Medical-grade EKG and Fits in your Wallet

Say goodbye to that chest strap heart rate monitor, and say hello to the future: a credit-card sized EKG reader designed to fit in your wallet.

The device is FDA-cleared to detect atrial fibrillation, and can recognize the six most common arrhythmias, along with tachycardia and bradycardia.

You can store it in your wallet or the MagSafe case on your smartphone, and whip it out for a quick check anytime you’re worried your heart’s not quite beating right.

Rest your thumbs on the two panels, and within 30 seconds, your phone will receive the EKG data via Bluetooth so you can see what’s going on.

It’s an exponentially cheaper option than a heart rate monitor, fitness tracker, or smartwatch, and it’s portable enough you can take it with you everywhere you go.
