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.

Need to reset a VeriFone 3750 v501 to its original default state. The program password has been changed and I cannot access to update


Turn off and unplug the Verifone 3750. Wait for five seconds or so and then plug it back in. This will automatically reset the Verifone 3750 and it will reboot and restart.

Reset the shift. Resetting the shift is another reset option available for Omni. Press "Shift," then "#," followed by "1" to reset and change the shift.

Press "Shift," then "#," then "2" to stop a change and keep the shift on the current settings.
Below is your user/install manuals, it's all in there so download each copy for any time later.

My enter key no longer works on my 2 year old Omni 3750. It seems like it is not making contact consistently. Everything else on the unit works very well.

The features in your terminal are run in conjunction with servers at your processor or gift card provider. You cannot use those features openly with your internal loyalty program. I could set it up for you give me a call and I will give you the details on it.
