Google wallet

The predecessor to both Android Pay and Apple Pay is Google Wallet. First released in 2011, it serves all the mobile functions as its contemporaries and is accessed when mobile phone users download the app. Recipients don't necessarily need to have the app themselves to receive funds, though, because money can also be transmitted via text, or email address. But of course, for the funds to be accessible, the receiver must have a bank account, similar to how PayPal works to both send and receive financial transactions. While these accounts are typically linked to savings or checking accounts, Google Wallet allows users to make payments with credit cards as an alternative.
