MagTek Dynamag Card Reader (USB for Desktop/Laptop)
If you are on a Mac, we've found that the MagTeks will occasionally require a one-time PC connection in order to switch the device into Keyboard Emulation mode. If you aren't able to successfully swipe a card number into Text Edit you will likely need to contact your supplier for steps on updating it to Keyboard Emulation mode.
Credit Card Reader Setup Information:
You must have a "Card Present" account with Authorize.net, which is probably not the standard account type you may already have. We got one for testing it was only $20/month and a few pennies when you do more than 100 transactions.
Once that is setup, and you check the box to 'enable authorize.net' in the settings, your payment form will default to credit card. Swipe the card in your reader with the cursor in the credit card number field.
If the light is green and nothing happens after you swipe the card, it's probably in "HID" mode instead of "KEYBOARD" mode - no problem!
Just head to magtek's website on Windows and change to "keyboard mode", in Internet Explorer: http://magtek.com/support/mode
