For those providers who are using the MagTek single check readers these act as keyboard emulators so after they are plugged into the computer, a driver is installed automatically and no other software will need to be installed.
To use these devices you would go through the payment flow as usual. Once you arrived at the payment information screen you would select the eCheck option. After this select the Routing Number box. Once the cursor is here, go ahead and slide the check through.
When inserting the check, make sure to have the scan line on the bottom and facing inwards on the device. Also insert the check evenly so that it reads in correctly. If it is inserted at an angle it may not read all of the data on the check.
Once this has been read, it will populate the page and submit the payment.
