"Apple Pay will ignite consumers' interest in mobile payments by providing a seamless, secure and easy way to pay both in store and on the go. By partnering with the leading merchants across retail, grocery, drugstore and dining, consumers can use Apple Pay with merchants they shop every day - which will accelerate the growth of mobile payments in the US," she said.
Outside the US, Carrington's caution is reflected by other industry stakeholders.
Dave Hobday, managing director of Worldpay UK, suggested that retailers should boost investment in new payment readers "when it's clear customers are ready to use them en masse".
With figures from Forrester showing that the Apple OS market share in Europe being just 17 percent, with Android's expected to hit 67 percent this year, the time for investment to accept Apple Pay in stores may not be some time.
"We've seen a 248 percent increase in contactless payments since 2012, but it's taken eight years to get to a point where consumers are comfortable enough to really start using the technology," Hobday pointed out.
"There's no doubt Apple has the clout to change consumer behaviour, but we're not yet at the stage where retailers will lose a sale because they can't take mobile payments."
Don't adopt technology without a business case
Digital River World Payments, which offers global payments and processes more than $30 billion in online transactions globally, agreed that the Apple announcements around Apple Pay raised more questions than it provided answers.
"The payments market has been inundated with new wallets and technologies in recent years and, with no clear winner among consumers, many merchants have found it difficult to decide what payment offerings to invest in, and when," said Souheil Badran, senior VP and general manager for Digital River World Payments.
"If Apple can succeed in this space, and offer a ubiquitous solution, it could help simplify the landscape for many merchants. Ultimately, long-term prospects will depend on how it will work with existing payment technologies, and, of course, user adoption."
Other analysts have warned retailers against making the mistake of adopting new technology for technology's sake - a pertinent lesson for businesses about all technology, not just Apple's.
"Before anything else, retailers need to understand what their goals are in implementing any mobile payments or point-of-sale (POS) strategy," said John Gessau, mobile payments solutions lead at global payments company ACI Worldwide.
"Retailers should see the current mobile disruption as an opportunity to review their overall omni-channel payments strategy. They would do well to avoid leaping into such a volatile environment, deploying a solution that will not meet their needs, only to find that they require a 'rip and replace' down the road as the market evolves."
