Hmm I have a Visa connected directly to my bank account, (debit?) So far so good, but i also have an app on my phone (Android) from my bank (Handelsbanken) that lets me check/transfer money from my accounts. But i can also LOCK my Visa from being used outside of Sweden and on the internet. So every time i want to buy something on the internet or going to another country i open the app open my card for internet/international use and tada.

This service is free and i can Unlock/lock my card as much as i want too.
