Question about VeriFone Omni 3700

1 Answer

Our verifone omni 3750 credit card terminal started making a beeping sound and would not accept input. Sometimes you can unplug it and then it will work fine or you can press many different keys at the same time and this will stop the beeping. Our challenge is if it is acting up at closing we can't get a batch done. It almost seem it has key jamed but none appear to be. Any ideas?

Depending on the type of business you are, the terminal can get pretty dirty on the inside and not look it on the outside. I had a florist contact me about similar issues with his terminal and after a good cleaning of the contact points under the pin pad the Omni worked fine.
Good luck

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.

Verifone OMNI 3750 gives error message: NO MASTER KEY


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.

Wanting to use the loyalty feature on the Omni 3750


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.

Verifone Omni 3750, set up problem


Your processor should be able to essentially blow out the memory on the terminal. From their a dummy program can be loaded to finish wiping out any residual memory. Lastly, you will need to do a completely new core load with your actual file build. The process takes much longer than normal due to the multiple core loads but it is effective. If your processor is not familiar with this or is unable, I would be more than happy to take over your services but am unable to solicit on this site. So, feel free to email me with any questions you may have at CJepson@federal-financial.com. Hope this helps.
