SOURCE: device is showing tamper detected

I repair these units for a living. The tamper if it's an 870 or greater is either a security pill, ped fence, battery. You need a volt tester because more then likely it's the battery. If it's an older unit there is a 90% chance it's the battery.

If it's the battery you need a SGun and a new battery. They are very easy to work on. To clear a tamper once the battery has been installed you will have to do a hard re-set, take a small pen or needle and hold the reset button on the top right corner down 3-13 times. I repair 18 of these in 8 hours and I always wait for it to blink 13 times before letting off the reset button.

If you do this the unit will need a reload of your software, that's a whole other ballgame if you have custom software on it. When you hard reset a unit your basically stuck with RF 15-16-17 and whatever service pack is currently on the system.

SOURCE: How can I solve the problem **tamper** in Verifone Vx510?

Verifone has a built in safe-guard against tampering. There are certain things that can cause the new Vx Series of terminals to display this error - from someone actually tampering with the terminal, to a physical drop or jarring of the terminal.

I hate to be the bearer of bad news, but the ONLY way for a terminal to be unlocked when displaying "Tamper" is to send it into an authorized service center. I have many of these devices in the field for customers and have dealt with this issue a few times - unfortunately, that's the only way Verifone set it up for this error to be resolved.

Sorry for the bad news, but hope it helped!

Yes your assumptions are correct.The unit does not store the customer information as that will be illegal and amount to fraudulent activities. Also it is highly secured so the merchant ID is completely inaccessible.
Hope this solution has been helpful?

SOURCE: tamper will not clear

For you to be able to reset the the unit, you need to install or replace the MSAMs where all previous information is stored. Here are additional steps that you may apply to reset the unit.

1 Remove the power cord and/or battery (see Smart Battery) from the terminal.

2 Place the terminal upside down on a soft, clean surface to protect the lens
from scratches.

3 Remove the MSAM compartment door screw and rotate the door up and back
to access the MSAM cardholders

4 Remove any previously installed MSAM card by sliding the card from the
MSAM cardholder.

5 Install an MSAM card by aligning the card and carefully sliding it within the
guides on the cover until it is fully inserted

Installation guide
user manual
you will find all info in those two manuals..even the factory code used in resetting mode...if it is not will be 998877

NO we cannot solve it onsite. The battery needs to be replaced and check plastic case as well as the sensors inside. After that, reloading the Verifone Software will clear the tamper error. If you still need help, you can call us at (775)358-2922 ask for Randy. Thank you.

Tampering detected 20000

Verifone units has multiple sensors built inside for security reason. If you acceidentally dropped or jarred the unit, the sensors will kicked-in and give that error that you have now. And i'm also thinking about your internal system battery is getting low too and needs to be replaced. Then we need to reload the Verifone Tamper Removal Software to clear the Tamper error. Tamper error can be cleared, if you still need help you can call us @ (775) 358-2922 ask for Randy. Hope to hear from you. thank you.

I need to unlock a NorthAmerican Bancard Verifone vx570. Z66831 only gets me past the first password inquiry and not the second

If that doesn't work, try "BEERTIME" or "23378463. if that still doesn't work, all we can do is flush the old program by opening the machine and disconnecting the internal battery, BUT TAMPER ERROR will come up after doing that and the verifone program needs to be reloaded to get the tamper out. Call (775)358-2922 look for randy and maybe we can help you
