Shares of Internet payment company PayPal slid Wednesday afternoon, closing down 1.8 percent after a report that Apple will roll out a mobile person-to-person payment system.

Apple is in talks with U.S. banks to develop a service, similar to Paypal's Venmo, that would allow consumers to "zap" payments from their checking accounts to recipients through their Apple devices, The Wall Street Journal reported. Apple declined CNBC's request for comment.

JPMorgan Chase, Capital One, Wells Fargo, and U.S. Bancorp are among the banks speaking with Apple, the Journal reported. The move comes as the tech giant's existing mobile payment application, Apple Pay, is expanding. After launching earlier this year, it has moved to drugstores, and more recently, to restaurants like Starbucks, KFC and Chili's, NBC News reported. A new peer-to-peer service would expand users' ability to make mobile credit and debit card payments to not just businesses, but also other individuals, the Journal said.
