This question is for POS 2.0 Merchant used stand-alone terminal for few days to process credit card transactions while testing and setting up POS system. Now that POS system is good to go, wondering how to enter those previous credit card transaction in POS system? If credit card information is manually entered it will charge customer twice. If entered as cash, it will be inaccurate tender type for accounting purpose. Is there anyway to enter previous credit card transactions without charging customer twice while maintaining accurate accounting? This may be necessay in future also in the situation when their internet connection or computer goes down for some reason and they use stand-alone credit card terminal to process transactions. How would they re-enter those sales in POS system in order to maintain inventory and accounting as accurately as possible?
Taking voice authorization is one option, but it is time consuming especially when a merchant is busy with several customers.
