RewardsPay, Inc., the payment platform that enables redemption of loyalty and rewards points at online merchants, has teamed up with Coinbase to allow customers to pay for products at its online merchant sites using bitcoin.

Merchants enable bitcoin payments by allowing customers to select the RewardsPay payment button on the checkout page of their website. Customers decide how much of the payment to make with bitcoin (and can also combine payment with a credit card). RewardsPay then facilitates a real-time split-tender transaction drawing from the customer's Coinbase account.

"Adding support for Bitcoin was one of our most exciting projects to date," said Anu Shukla, founder and CEO of RewardsPay. "Coinbase is an ideal partner due to their bank-level encryption and high security payment processing. We are confident in their technology and also excited for the business that this will bring to our merchants."

The RewardsPay website lists nearly a dozen partner merchants, including: Overstock.com, iTunes, Facebook, World Golf Tour, Heels.com and others.
