Apple Pay can boast the highest merchant support of all mobile wallets currently on the market, according to a report from Boston Retail Partners.

Apple Pay is accepted by 36 percent of U.S. merchants, followed by PayPal at 34 percent, the report said.

At least one-third of merchants are taking a wait-and-see approach to major digital wallets.

"One of the critical factors for any mobile payment success going forward is education," Boston Retail Partners said in a statement about the report. "We have found repeatedly that not only are consumers unsure of how and when mobile payments can be used but, even more telling, associates are unsure."

Boston Retail Partners surveyed the top 500 retailers in North America for the report.
