Google will retire its Checkout payment processing tool on Nov. 20, and warned retailers they will need to move to a different payment processing platform.

Checkout, which launched in 2006, was merged with Wallet, which is a mobile payments tool, last November. The product was aimed at taking on eBay's PayPal service, which dominates Web-based payments.

Google said it has partnered with Braintree, Shopify and Freshbooks to offer discounted options for retailers that have not yet selected an alternative payment processor.

Wallet will now be the company's focus. Developers for its Play store will be moved to the Google Wallet Merchant Center, Justin Lawyer, senior product manager for Google Wallet, wrote. There will be no changes for consumers using Wallet on sites such as Priceline and Uber, according to Lawyer.

U.S. merchants who do have a new payment processor can apply for Wallet's "Instant Buy" feature, Lawyer wrote. Instant Buy, which was formerly known as "Google Wallet for Online Commerce," allows consumers to share their payment details with merchants.

Wallet stores users payment details and is also capable of performing contactless payments with NFC-enabled Android devices.

Last week, Google announced it had integrated Gmail with Wallet, allowing U.S. users to send money to each other. Transfers made from a bank account linked with Google Wallet are free.
