PNC Financial Services Group Inc. has struck an ATM branding deal with Cardtronics Inc.

The Houston automated teller machine operator said Thursday that PNC's brand would appear on the money machines it operates at all of Hess Corp.'s 230 service stations in Florida.

Customers of the Pittsburgh financial company will be able to use the ATMs for free. Branding deals like this are considered a cost-effective way for banks to expand their ATM presence without purchasing or operating the machines.
