However, the CBA is still insisting that Apple should give it access to the near field communications controller so that it can set up payments, a demand that Apple is unlikely to grant.
A report in the Australian Financial Review quoted Matt Comyn, the head of retail banking at CBA, as saying the fee that Apple was asking for use of Apple Pay was not the main hurdle to cutting a deal.
He said: "If we could get access to the NFC antenna and our wallet had the same experience [as Apple Pay] on parity, there is no way the interchange fee, as currently contemplated, would be the stumbling block."
The sticker costs $2.99 and Comyn said 400,000 customers had ordered them but the latest numbers showed 600,000 transactions had been made per month.
The CBA, along with Westpac, the National Australia Bank and Bendigo and Adelaide Bank, have been denied permission by the Australian Competition and Consumer Commission to negotiate as a cartel with Apple over Apple Pay.
Apple has repeatedly said it will not allow direct access to the NFC controller.
