Facebook is planning to create a feature that will enable users to make in-store purchases through its Messenger app.

A code tucked inside Facebook's Messenger indicates how the chat app could become a market place, where users will be able to bypass credit card terminals in a store, with possible other unreleased feature which includes "secret conversation" a likely similar to WhatsApp's recent rollout.

Facebook may have a large team working on the project, which will soon allow users to pay for items in retail stores where Facebook's Messenger app authorizes the credit card transaction.

It wasn't made clear how the service will work, but according to chief executive of Facebook Mark Zuckerberg claimed last January that the company might build up a partnership with Apple in the likes of creating the payment service by means of in-app purchases.

Facebook's initiative is to create a system that will allow users to easily connect with businesses, offering the social networking giant a potential to demand payment for ad space.

Mark Zuckerberg said, "We'll partner with everyone who does payments, we look at the stuff that Apple is doing with Apple Pay, for example, as a really neat innovation in the space that takes a lot of friction out of transactions as well."

However, if Facebook wouldn't be able to strike a deal with Apple Pay, the new service would remain a competitor by default, where the mobile payment industry such as Android Pay and Samsung Pay has been active to compete for a position, yet a survey appears to show that Apple Pay is by far the most desired payment service.

Apple is also showing plans to expand Apple Pay that will soon support purchases through Safari's browser, where the company suggested with potential partners in expanding its payment service to websites that will enable shoppers to securely complete a transaction for goods and services.
