Yes, it is. djhworld is laughably wrong. All the contactless systems Visa/MC/Amex are deploying in the world are variants of PayPass/PayWave which are all based on an international standard and will work no matter what. The article djhworld linked to is talking about how users in the UK won't be able to add cards to Apple Pay because Apple doesn't have any deals with UK banks. If you go visit the UK and have an already-enrolled Apple Pay account, it will work at contactless terminals.
