Q: Fraud and transactions security with Apple Pay

Hello there,

I have a few questions about Apple Pay.

I would like to know how it handles the transactions made with different kind of card such as (for example) :

- Classic Mastercard

- Gold Mastercard

- World Elite Mastercard.

Indeed, payment conditions depends on the type of card, they also depend on the bank of the card owner (for example : number of allowed transactions or maximum amount before an authorization request or a PIN code request). Those conditions are stored on the chip of the smartcard and so I would like to know how Apple Pay replicates those conditions, or if it has its own conditions regardless the card and the bank. Though in that case, if there is a fraud transaction (eg : the card has been blocked by the bank but a contactless transaction has been made), who is responsible for the fraud ? Apple or the bank ?

Thank you for your answer.
