We use the tablet at the front desk to take payments for 3D printer build plates ($5), orientation ($10), and affiliate day passes ($25).
On the desktop you will see an icon called “REGISTER”. Open this. On the right you will see a list. Click “All items”. Then you will see the possible choices listed and you can tap the item they want to purchase. If it is something that is not listed, click on “Keypad” so you can manually type in the amount to charge.
Once your item(s) are chosen you will see a blue box on the bottom right that says “Charge –whatever the amout is–”. Now swipe the credit card through the small white square device that is plugged into the tablet. The card will then be charged. Now the customer signs the screen with their finger and then have the option to have a receipt.
