Greggs’ contactless is down today at Finsbury Park. My own Monzo and Virgin Money cards, plus the people in front of me (I recognised a Santander card so probably a Visa and another Monzo card).
The odd thing is… Contact was working fine (maybe a bit on the slow side but normal-ish) The message was ‘declined’ but it took a long time to get there and nothing shows in the Monzo app so I guess the authorisation message never got through to Monzo.
What can possibly cause contactless to have an outage (when it normally works) without that same outage affecting contact?
This was on both of Greggs’ terminals at least at this location. Thus it was probably far more widespread and definitely not a terminal issue.
Even if it was a terminal issue, I’d expect a card read error for a terminal problem. Not for it to get as far as authorising then fail.
I wonder if your dog groomer and Greggs use the same processor? They may be having issues? It still seems so weird that processor issues could affect only contactless.
Contact doesn’t necessarily involve a PIN (though it does in most cases with UK issued cards being used in the UK, unless you request a signature card for accessibility reasons). Also contactless can be used for ‘chip and PIN’ (by using online PIN instead of offline PIN). Thus it’s better to say contact instead of chip and PIN because chip and PIN could still be contactless but doesn’t encompass all contact transactions.
