The British "bank" is a simple pre-paid card which customers transfer money from an existing bank account to allow advantage of its apps, Engadget.com reported.
Although Monzo has given its support for Android Pay it is currently only available for people with a current account.
In April, it was approved by UK authorities making it just the same as a real bank and even offers proper accounts.
Since then, the system has been inviting pre-paid card owners to switch over and now with Android Pay, Monzo looks to be making things easier for British people to switch away from high-street banks.
To connect Monzo with Android Pay, user must add in their card details manually or by taking a photo of their card.
After, this will allow users to make contactless payments using their phones and Monzo will track the spending and list transactions in the "spending feed".
The company also hinted users will soon be able to add cards to Android Pay from within the Monzo app as well.
Monzo's support for Android Pay comes after rivals including Starling have given their support to both Apple and Google's payment platforms.
