Android Pay, a simple and secure way to make a payment using an Android phone, has been rolled out. The announcement was made, Thursday, on Android's official blog site.

Let's take a look at the features of Google's new app.

1. Who can take advantage of Android Pay?

Users running the version 4.4, also called Kitkat, or up will be receiving the update in a gradual manner, Google told USA Today. Over the next couple of days, it will begin to show up in the Google Play store and should be available to all users in the middle of the week.

It says in Google Play Store that the Google Wallet will be updated to Android Pay in the next few days.

2. What does it support?

Android Pay will support credit and debit cards from American Express, Discover, MasterCard and Visa, which are issued by many famous U.S. Banks and credit unions, such as Bank of America, Navy Federal Credit Union, Regions Bank, American Express, Discover, PNC, USAA and U.S. Bank. Wells Fargo will reportedly be available next week, while Capital One and Citi are coming soon.

3. Where can it be used?

Android Pay can be used in more than one million retail locations in the United States, including American Eagle Outfitters, Coca-Cola, GameStop, OfficeMax, Subway, Walgreens, Toys R Us and more, Luxury Daily reported.

4. How do you use it?

The experience is reportedly similar to Apple Pay. The Android user can store the credit card into the app and simply tap the phone at a Near Field Communication (NFC) terminal to make a payment.

Android Pay is reportedly not requiring a fingerprint scanner to authorize the payment. A four digit pin code, just like at an ATM, will do.

5. What if there is a security breach?

Google is supported by industry standard tokenization, according to the report of The Science Times. After the card information has been entered into Android Pay, the app will generate a code called a token.

Each card reportedly has its own token code, and each token is specific to each Android. If a purchase has been made, the token will be creating a new token, which will be used temporarily to complete the transaction.

The app can be secured in Android Device Manager, in cases of stolen or lost phones.
