Groupon has updated its Android app for merchants to incorporate Groupon Payments so they can accept credit cards with it.

Groupon says the service can be activated within minutes, and can be used to enter bill totals, add tips, apply taxes, process refunds and email customer receipts. It’s backed by Groupon’s 24/7 support team, which can be reached by phone or email.

“We’re thrilled to bring the powerful features of the Groupon Merchants app and the cost savings and convenience of Groupon Payments to more merchants with smart phones,” said Gene Alston, General Manager of Groupon Payments. “This app is an effective tool for merchants looking to process payments and track customer growth.”

The app encrypts credit card info for security, and provides analytics, looking at live transaction history, daily sales reports, deposit tracking, and revenue trend analysis.

The app is available in Google Play. The service is already part of the iPhone app.
