Mark Carroll's Journal

Thank you. They look plausibly interesting though amusingly unclear in the how it works. I wish more regular payment card providers offered that kind of service built-in (virtual card numbers with constraints). So far I've had very little practical trouble mostly because I carry a range of cards so, while I wait for dispute resolution on one (which happens only every few years), I still have plenty of credit elsewhere, like the jolly time HSBC locked one of my cards just as I was heading out on vacation. So far everything problematic I've had reversed without issue but that's a small sample size.
