@TimWardCam@c.im Lots of comments arguing that this is not what people are complaining about, so I felt I should point out whatever system my cash back for groceries card is using for fraud detection is an absolute sack of shit, excelling at both Type 1 *and* Type 2 errors.

@siderea@universeodon.com @resuna@ohai.social @yugthebug@mastodon.social @jmax@mastodon.social @thirstybear@agilodon.social Yes, there are several suppliers of such systems in a highly competitive market and some are better than others. The systems are largely sold on false positive rate - false positives are expensive, because they piss off your customers and you need to pay humans to man a call centre to deal with the complaints.
