Payment refused in San Francisco


I tried to pay with my revolut card in 3 shops and they were refused. There were with a machine which read the chip. It is ok with machines which read magstripe.
Is somebody know the reason ?
Thank you for you help


What decline reason does the revolut app say? do you have location based security? if so, try disabling it.


No reason only declined.
Yes I have location based security but this evening I tried again in the same shop where this morning a purchase was declined and it was ok ! !
Thank you for your help


Hmm we can always investigate the reason for a decline if you reach out to us on support chat. Sounds like there may have been a connection issue if this transaction worked for you later.
