The Cash Passport experience over the last few years has been pretty mixed. On the one hand, it's a functional card that supports a wide range of currency and works pretty much everywhere. On the other hand, the websites used to view balances and reload currency always feel like something a scammer cooked up in a basement somewhere, and they never work quite right. Whenever I've loaded more cash onto my card I always want to have my partner double-check the page, the site, and my browser, to make sure I'm not being taken for a ride.
Aside from all that, the Cash Passport is an extremely useful travel instrument.
