I mean if you can get your colleagues on Revolut, that already pretty much takes care of everything. Most places allow paying by card, and some payment gateways already let you save your card so even if try to pay somewhere else but it uses the same payment gateway, you can reuse information fairly quickly.

Your browser can also keep payment card information - optionally (and I recommend this) in the OS keychain rather than in some plaintext file. But I do have to tell you here that since I don’t use it, I haven’t looked at any browser’s implementation to check if it’s secure for real or not.
