Has anyone here used SumiTrust Club Card for online shopping, eg booking onsen, buying flights?
The 3D Secure authorization system often doesn't work. I phone customer service to double-check the card isn't locked. I clear the cache on my browser and try using another browser. I try turning off ad blockers etc. in case they are blocking the pop-up prompt for the one-time password. Nothing solves the problem.
I don't have this issue with other credit cards. The code-generator app looks like something out of the 90s.
Just wondering if others are having issues shopping online with this card.
