Alternate way of processing credit card order

Is there a another method of processing Credit Card oders?

We have a situation where a customer (walk-in), orders a product and pays by credit card. Our system puts the order on hold automatically. We do have another teammate that can release the order. The problem is this is happening in another provice, and we are in another, and the backup person is away, and we are losing the order, as we could not produce the paperwork, and get customer his product even through the credit card had been processed and authorization obtained.

I am looking for alternate ways for processing these one-time orders, and what the setup would look like.
