Big companies like Walmart are fighting adopting new credit card technologies since this is their opportunity to pay less fees. In Australia, fees are typically below 1%. e.g., Visa Australia charges .275% to supermarkets and 0% to charities. http://www.visa.com.au/aboutvisa/interchange/interchange.shtml http://www.visa.com.au/aboutvisa/interchange/interchange.sht... In the USA, it's typically over 1% (see page 7) https://usa.visa.com/dam/VCOM/download/merchants/Visa-USA-Interchange-Reimbursement-Fees-2015-April-18.pdf https://usa.visa.com/dam/VCOM/download/merchants/Visa-USA-In... On the other hand, this is why Australia hasn't yet adopted Apple Pay. Apple want the same cut of the total transaction, (I think it's 0.15%) which is more than half of the total fees charged in Australia in most cases.
