PayPal is a giant when it comes to online financial transactions. Its reach even extends to mobile, allowing millions of its users to do their transactions on the go. Then there's Android Pay, a payment service by Google. The application lets people pay for their purchases with one tap to near-field communications (NFC) technology outlets. The two have been competitors in that field until they decided to team up.

Both Android Pay and PayPal give users the option not to use cash or whip out their credit or debit cards upon payment. Instead, they input their payment data into the applications and use the mobile applications to pay. Now that they are working together, people can start linking their accounts from both services.

On the launch date, Google Pay can only support a user's available balance. Cards linked with PayPal accounts would not yet be supported. However, both parties are working to include those in the future. TechCrunch also adds that the integrated service can work in any place where Discover is accepted.

This partnership is beneficial to both Google Pay and PayPal because it gives the two services leverage over their rivals. As of now, their most formidable opponent when it comes to point-of-sale is Apple Pay. The latter has been dominating that area and the number of users has almost doubled year by year. Unfortunately, it does not support PayPal integration.

Furthermore, there is Samsung Pay, a lesser known and less used application, Fortune notes. It has limited reach at the moment but its number of users is expected to reach 34 million by the end of the year. On the other hand, Android Pay's projected number of users is 10 million less than Samsung. But Samsung's mobile payment service also does not work with PayPal.

The Android Pay with PayPal support will be available to devices running Android OS 4.4 and higher. This will include mobile gizmos powered by KitKat, Lollipop, Marshmallow and Nougat.
