some feedback on my UBS Visa card (Optimus Foundation):
CHIP+PIN works at my local garage (in the shop) but normally I have to sign. Deffo abroad need signature.

M-Mastercard CHIP+PINs all over - but they gave me such a shockingly low limit that it's maxed out all the darn time.

I should have Postfinance Visa to test this week. Bye-bye, UBS
