Mobile Merchants using their iphone 3G (or iphone 3GS) and the Payware Mobile encryption sleeve to swipe credit cards have a few program options they should know about.

The slide time out function and the submit after card function. You can find these card reader program options at menu, set-up, secure card reader on the iphone 3G, 3GS.

Here is a look at what they do.

1. Slide Time Out is the amount of time the application allows the user to swipe the credit card. There may be times when there is difficulty reading the credit card track data. The default value of 30 seconds can be adjusted for a longer period of time. However, longer slide time out times can deplete the smart phone battery charge faster.

2. Submit After Card- When this feature is turned on, the credit card transaction will automatically be transmitted to Payware connect for authorization after the card has been swiped through the card reader. The submit after card function eliminates the need to push submit after each transaction.

Most merchants will not need to change these default settings, but it never hurts to know your card reader options.
