Anyone happen to know if chip and pin cards work after a wash at 40 degrees?

Someone else must have been as daft as me, surely?

My partners regularly gets washed with his whole wallet and seems to keep on working well

No idea, sorry.

Mine have always worked after a wash

Yes

You can tumble dry ones from barclay and they still work (twice )

Yes, mine has been fine- Parking the car on top of it is not recommended, however.

You can also wash and tumble dry air pods (or so I’m told )

Yep.

Other things that are fine:

AirPods
iPhones
Apple earphones.

good, good .
I won't panic order a new one then, and will try to remember to give it a wee test locally before I need to rely on it.
