We were lucky enough to take a quick trip to Europe this summer and one of the many rituals of modern travel is convincing your card issuers not to block international transactions. The conventional wisdom is to notify issuers in advance. While not an absolute necessity, it is said to improve your odds.
The process is very straightforward. All the bank needs is your travel dates and where you are visiting. However, it is tedious over the phone due to redundant authentication requirements.
Consequently, it's an ideal service to automate with online, or even better, mobile form. I wrote about it the last time I traveled. But this time I put a clock on the process, just to see exactly how much time was wasted, for both the consumer and bank, on the phone.
