I don't use it that frequently, the last charge was a payment to Aliexpress...
The limit on that card is £10k
i'd stick with one-time virtual card for online payment. Secure and cheap (1$ or even less).
so, the scenario is always the same: sum up the totals, issue the virtual card with hardly defined limit which is just slightly higher than the totals. Once payment is made, i terminate it.
almost easy and bulletproof solution so far.
however, IRL the things are too scary: skimmers inside of ATMs, fake terminals, etc. So, if CC gets copied, nobody'll never notice that, unless somebody tries to use a copy/info.
bad thing is that my CC comes with magnetic stripe. No chip inside. Also, i don't like to enter pin code every time i purchase something in local store. Safety and usability never happen simultaneously altogether :-) But you could trade some portion of usability for safety or vice versa.
