Hello Daniel,
If you're looking for an alternative to Mercury, let me introduce you to Velocity - the integrated payment division of North American Bancard.
Velocity offers an RMS plug-in that connects your application to our semi-integrated EMV solution. Included in our service is an auto close feature. You can specify the hour that you want your batch to close.
thank you,
Ed Dionisio
Director of Business Development - Velocity NAB
