A lot has been made about Apple's move to enable mobile payments through its new iPhone 6. But much of the discussion focuses on just one side of the equation: the convenience for customers, not what it means for merchants.

But for companies like Amazon.com (AMZN 1.49%) and Bank of America (BAC 2.06%), there are significant opportunities in the payments industry, especially when you consider the news in the context of a recent study on mobile payments.

The trajectory of transactions
In every payment transaction, whether it's at a major retailer like Wal-Mart or a small business down the street, a merchant is paying some company's merchant services division a fractional amount of every sale to allow them to accept that credit or debit card payment.

The Nilson Report revealed that in the U.S. alone, the total 2012 purchase volume of the 78 billion transactions stood at nearly $3.8 trillion. When you consider that transaction number is projected to grow to 120 billion by 2018, it is no wonder the payments industry gathers so much attention. 

Not only are customers now increasingly able to make payments with their phones, merchants for years have been able to accept payments with physical cards on both mobile phones and tablets.

A 2013 survey from Gallup reveals a number of surprising realities about the current state of that industry, which IDC projects will process $720 billion worth of payments by 2017. 

It's no wonder companies in the merchant services business have been diving into the mobile landscape with such incredible velocity.

A cheaper way to pay
Amazon made headlines in August when it announced Local Register, which the online retailer described as "a secure card reader and mobile app that provides local businesses with the tools they need to quickly and easily accept credit and debit cards from a smartphone or tablet and keep track of their growing business."

The biggest news came not from the product itself, which in many ways wasn't new, but from Amazon's intention to charge a transaction fee of just 1.75% per swipe through the end of 2015 for merchants that sign up by Oct. 31, and 2.5% after that.

Popular mobile payment service Square charges 2.75%, while the Clover tablet tool from Bank of America Merchant Services -- a Bank of America (BAC 2.06%) and First Data joint venture -- starts at 2.5% plus $0.20 and gradually progresses downward. So the service offered by Amazon dramatically undercut the industry standard rates for mobile payments.

This difference of 1% between the fees from Amazon and Square would mean an extra $10,000 in the hands of a small business owner who had $1 million in sales.

So why is all that important in light of the results of the Gallup poll? The first surprising insight was that just a small fraction of businesses actually use mobile payments:

This survey data is nearly a year old, so these numbers have likely increased, but the fact remains that there is a massive opportunity for financial companies (and, indeed, nonfinancial companies such as Amazon) to expand to allow businesses to process payments on a mobile device.

Even more striking in the Gallup poll was how distinctly dissatisfied customers were with their current products:

Knowing that such a small number of businesses can currently accept a standard card payment through a mobile device -- and an even smaller number are satisfied with the product they use -- illustrates a massive opportunity that exists in the mobile payment industry for merchants, and not just consumers.

Assuming the number of merchants that have the flexibility and capability to allow customers to pay with their credit cards anywhere continues to grow, why would there ever be any reason for a customer to make payments with their own phones?
