So twice over the weekend, I had transactions decline that I’ve then been charged for the next day.
1 - I tapped my card (not my watch/iPhone, like I’m from the 90s) I got a buzz on my watch but just thought it was the confirmation. It wasn’t until I checked my phone next that I realised I had the “You’ve hit your contactless limit, please enter your pin” message. Woo! Free food! The next day I got the notification that I was charged.
2 - I used ApplePay this time, but used the wrong card. Declined! Again, didn’t notice from the notifications. Then this morning I’ve been charged.
Both times the person using the machine didn’t say anything and then proceeded to give me my food and drinks afterwards, so wasn’t like I’d started walking off and they didn’t have the chance to catch me.
I’m not worried about the fraud aspect or reporting it as such, I had these items and I tried/intended to pay for them and if they’d have said, would have fixed it at the time. I’m just curious to learn more about how this works.
Have they just printed a declined/failed receipt and then typed my digits in manually the next day?
I recall discussing a similar case recently and I’m sure it was something to do with how they send the request through the payment system and have to prove you owe it to them.
If it’s the latter, most likely although it said declined on Monzo, they registered it as successful and then you just got a presentment through. Happens occasionally.
