Yet another smart card has found its way onto the market. While the Stratos doesn't have a screen, it has a few other differentiating features that may separate it from the others. Namely, the fact that it boasts track 1 and track 2 data which means near universal compatibility compared to others such as coin, which have a slightly more limited market.


  • Slim as actual credit card.
  • No need to charge.
  • Track 1 and track 2 data
  • Backwards compatibility with existing merchant hardware. No NFC required.


  • Must purchase new card when battery dies.
  • Still some merchants not compatible.
  • Possibility to get damaged in wallet
