COLORADO SPRINGS, Colo. – The $1.3 billion Ent Federal Credit Union has rolled out ePSCU's bill pay service, EasyToCUPayLink. ePSCU is the Internet division of Payment Systems for Credit Unions, Inc., St. Petersburg, Fla. What's interesting about Ent's move to EasyToCUPayLink, is it is the first credit union to support the single sign on method of accessing CheckFree's bill payment services. CheckFree is an ePSCU partner. Single sign-on enables an Ent member's secure Internet banking user ID and password to carry through to access the CheckFree system. After an Ent member completes the Paylink enrollment form, which is hosted by ePSCU and custom-branded for Ent, that member is instantly activated to use CheckFree's bill payment services.
