Facebook has been promising some sort of payments solution for WhatsApp, and it seems to be making a bit of progress in Indonesia.

According to reports from Reuters, Facebook is in discussions with several potential partners to offer a mobile payment feature in the app in Indonesia. Although this is not Facebook’s first venture into mobile money, there is a stuttering initiative in India, the Indonesian experiment will focus on creating a digital wallet to tap into one of the worlds’ fastest growing eCommerce markets.

Earlier this year, Facebook CEO Mark Zuckerberg suggested to investors a wander towards mobile money was an ambition of the business, though this should actually surprise few. When you consider the success of Tencent-owned WeChat in diversifying the offering of the messaging app, Facebook is playing catch-up.

For those who haven’t used WeChat, what you can actually do is quite remarkable. The app was solely focused on messaging to start with, but now you can send images, make phone calls, peer-to-peer payments are included, as are in-store purchase via NFC and paying utility bills. Soon enough, cards could become redundant, such is the growing usage of mobile payments through digital wallets and WeChat.

If Facebook could capture a slice of this success, WhatsApp might start to begin paying off the $19 billion Facebook had to fork out during the acquisition.

The original purchase of WhatsApp was seemingly a means to capture a messaging application which was taking the world by storm. However, the data which WhatsApp would have offered the Facebook advertising machine would have been very beneficial. The team has found integrating the two platforms very difficult to date, though mobile money is certainly a way of creating additional revenues.

In Indonesia, the Facebook team is in discussions with several partners to tap into the eCommerce platform, though in India it is focusing on peer-to-peer payments in-app. There are several reasons for the differing approach, regulatory barriers being one, though experimenting with two ideas could offer two new features for a global rollout.

Interestingly enough, something which might get the White House twitchy is the alleged conversation with one of the potential partners; mobile payments firm DANA, which is backed by Ant Financial, an affiliate company of the Chinese Alibaba Group. Considering the current relationship between Washington and Beijing, these must be interesting conversations.

Globally, this is a very good move from Facebook. According to data from Sensor Tower, WhatsApp was the most downloaded application during the first quarter, with 223 million new installs, taking the total north of an estimated 1.5 billion users worldwide. This is a massive addressable audience, representing huge potential if the team can get all the moving parts to align.
