We need someone to program a custom Verifone Terminal application that will allow the terminal to display a basic list box sales screen which we can send line item details to and it will display in real time to the customer as each item is added to the sale. There will also be a total sent from our application for display. These are all standard features of the terminal. The catch - we want the customer to be able to swipe their credit card at any time while this is being displayed.
Then, once the sale is complete, our application will use the SimDLL .process command to tell the terminal to process the card and collect the signature. Again, all standard features. The only difficult part that I have not figured out is allowing the user to swipe the card at any time during the sale.
Since we don't fully understand the terminal interaction, we are unsure whether you, the programmer, will need to work exclusively with the terminal, or if you will also need to work on a desktop application.
Please contact me to discuss what you believe the terminal capabilities to be related to this project so we can establish appropriate specs before project starts. You will be working with a software engineer on our team.
We believe this will be a relatively small project for someone with experience in Verifone terminals.
