E-commerce might be trending on Twitter soon. The social network appears to have plans to add shopping, according to information revealed – perhaps unintentionally – through its mobile app on Monday.

In the settings for its Android mobile app, Twitter Inc. (NYSE:TWTR) appears to have been tinkering with a “Payment and Shipping” option. Such a menu in other apps allows users to include their address and credit card information to make purchases.

Dozens of users noted the dormant function, which appeared only for some users. Twitter had reportedly been looking at retail features for the past few months, with Re/code reporting that tweets from retail sites that included an inactive “buy” feature in June. In January, the site obtained documents that showed Twitter had partnered with credit card processing companies.


Following some good news for Twitter’s second quarter, plans to expand into retail might please investors who are optimistic but concerned about the site’s ability to capitalize on its user base. The plans should not be a major surprise to the site’s close followers: Twitter partnered with Amazon.com Inc. (NASDAQ:AMZN) in May to allow users to add products to their shopping cart without leaving the social network.

Facebook Inc. (NASDAQ:FB) is also testing a new feature that enables small businesses to sell products through their posts and ads on the site's news feed. The company said last month the testing was limited to smaller businesses, to see if users were interested in having it store their payment information, and possibly helping companies launch an online retail presence.
