On Tuesday, the very popular Cash application by Square was updated to version 2.0 with a number of improvements for users.

Cash 2.0 brings with it an interface with speed improvements that allows you to easily send money to people using their mobile phone number. You can import your contact list for faster contact selection, or you can input numbers manually. All of the e-mail addresses and phone numbers that you send and receive from can be easily managed from one place in the application.

Other improvements include being able to add a note to any payments, being able to choose a profile picture for yourself, configuring all kinds of customizable notifications, responding to payments from those notifications, and more.

If you're interested in making a little cash yourself, this update will also allow you to invite friends and make $1 for every friend you invite that joins Square Cash.

Existing users of the Cash application by Square will find this update under the Updates tab in the App Store application. Alternatively, you can download the latest version of Cash for free from this App Store link.
