Today, Stratos announced it has begun shipping its smart credit card to those who preordered it.

The announcement comes just after competitor Coin has started to ship its connected card. Though Coin was the first to ship, it encountered delays along the way and is already fielding issues with its card. Of course, Coin isn’t the only competition in town. The connected-card arena features a slew of alternatives from players like Plastc, Dynamic, and Swyp. Stratos will also have to contend with digital wallets like Google Wallet, Apple Passbook, and PayPal, which increasingly have a physical presence.

Stratos enables you to compile all your credit cards on a single Bluetooth connected credit card that links up to a mobile app. To select a card, tap your Stratos card to your mobile phone screen twice to see options appear while your phone is still locked.

The idea is that one connected credit card is easier to manage and safer than a wallet full of credit cards. Stratos doesn’t display credit card numbers and you can remotely lock your card in the event that you ever lose it.

The company raised $5.8 million back in October 2014 in order to fuel production.
