Subitting Credit Card Payments in Batch

Hi,

Can anyone suggest a secure credit card payment service that a web application can use to submit offline transactions?

Most services only allow for a customer to submit their payments online as a single transaction. But what if I have accumulated several transactions from different customers, and want to submit them all at once? Does anyone know of a reliable service that accepts offline transactions?

Thanks.

cybersource payment manager can handle batch. but you need to write some code (in Java, for instance) to access the API.
