If it was a merchant or terminal issue then the physical card would not function correctly. They are.
When presented with the NFC containing data from the digital wallet the merchant is not able to make a choice. They are only presented with one option instead of two.
Dual network card: card can be used to process transactions through either the eftpos or credit networks.
Physical card: terminal sees two networks available and uses either default or merchant’s choice.
Digital wallet: terminal is only seeing the one option so can’t make a choice. It processes based on the one option it sees.
Consider a case where the merchant has chosen to route contactless transactions through the eftpos network. If the customer has a dual network card the terminal should see that and process the transaction as “eftpos savings” (this happens if you use the physical card). Currently with Apple Pay all transactions are being routed through the credit network as “Visa/Mastercard Debit” as the eftpos option is not being presented to the merchant terminal.
The merchant’s choice is not being applied because dual network is not functioning correctly with Apple Pay. The merchant is affected in the same way as the customer.
The problem is related to the information being provided by the NFC chip but it is still unclear whether it is the way the card is being provisioned by the bank or the way iOS is presenting the data to the terminal.
No one has an issue with the merchant choice part. It is out of everybody’s hands. The issue is that the merchant cannot make that choice because Apple Pay is not functioning correctly.
