The Google Wallet app is preparing to add multi-person money requests soon according to a teardown of the APK, where code revealed this and other upcoming changes to the application that users will be able to look forward to at some point. The multi-person money requests is the same as the feature that was added to Google Wallet on the web back in August. That said there isn't any indication of when these features will be added in but if Google is already laying the groundwork for them it probably won't be too long. For multi-person money requests it appears that everything will likely work as expected. You'll be able to ask multiple people for an amount of money at the same time and the app will calculate the total as well as show you how much you're asking for from each person.
In addition to multi-person money requests Google Wallet is also preparing for a reminders feature to be added in soon. With this feature you're basically setting up reminders to request money on a recurring basis every single week. You can also set up the reminder to work bi-weekly, monthly, or annually if you like, and the denomination can be as low as $1 and all the way up to $9,999. You're also able to add notes to these reminders so you remember what they're for. The reminders feature isn't really live yet, but the interface is accessible if you have a way to launch activities on your device. If you have Nova Launcher installed this a pretty easy process and you can just long press the home screen to add a widget, then look for the Nova activity icon, which will let you select an activity from the list. Here, if you select RemindersListActivity you can get to the Reminders screen where you can go through what setting one up will be like. All the functionality seems to work here save for the reminder actually being set up when you try to save it.
Also on the horizon is what looks like the ability to send or request money through Google's Android Messages app. This is pretty self explanatory, and will essentially be a way for people to send or request money in a quick and painless manner. If you're already in the Messages app and talking to the person you need to send money to or request money from, then there won't be any reason to spend an extra minute going to and opening up Wallet to complete the transaction. Alongside all of these upcoming features, there was at least one visual change to the app as well which you may or may not notice upon opening it. The main page where you have the amount of money you can enter to send or request is now using a bigger number than before, albeit only slightly bigger, and the number itself is now black as opposed to a gray color. This isn't a huge change, but it is a change. Wallet just recently went through an update, so this should be live in the Play Store.
