Question about VeriFone Omni 3700
We have two others. They work fine...just this one unit. We can find no mention of this error message in the instruction manual either. THANKS!
The no master key means that the terminal is missing a DEBIT encryption the debit encryption is needed to run PIN based debit cards. When you swipe it should say Credit F2 Debit F3. When you choose F3 it will say no master key. Whether you have an external pin pad or internal pin pad your credit card processor needs to inject with the encryption or take the debit prompt off.
If you have any other issues please don't hesitate to call me.
