To manually enter a credit card number on the Dejavoo Z6 credit card terminal, do the following:
Press the * key to access favorites
Look for an option labelled Spin Bypass
Select this and the Dajavoo terminal will bypass the POS system for that one transaction then go back to the POS online status and will require you to swipe / insert / tap card again.
If you do not see the Spin Bypass option under the favorites menu on the card reader or you have further questions regarding this process, you should call Dejavoo Tech Support directly on (877) 358-6797
