That terminal is useless. you need to send it in to have the "tamper" removed. The cost can be anywhere between $80.00 and $130.00. POS Distributers does ours. You could try to upgrade the operating system. That will remove it, but may not last....

You will most likely need to get a new signed certificate from the vendor, the certificates are used for secure transmission between the card processing company and you. Give them a call, they should be able to issue you a new cert and get you going again.

    That's not correct. VX-570 terminals say this when they get older and the software certificate expires. It is not a physical signed certificate. All you need do is press enter past the error and the terminal will start normally (if its already been downloaded with your merchant account information. - Jason Hanson, ePOS Merchant Services 888-560-9025 www.eposcc.com

We have a verifone terminal (not sure what model but I could find out) that keeps getting the tamper error. It's happened 7 times in the last 8 months. We've switching merchants which helped for a while...


Your problem presents more questions. Has your machine been refurbished during this time? Is the location in a restaurant or bar? Does the merchant turn off the machine daily? Does the machine get dropped often? These are all things that may cause the machine to go into tamper error. Please call Frank (775)338-6634

Verifone Vx570 given an error Modem Profile Not Set?


error modem profile not set appears when your Verifone VX 570 modem profile is not properly loaded or has been errased due to Tamper error or Bad RTC. Reloading back the modem profile will sometimes fix the error, but there is also a chance that your I/O module (form where you connect the power and telephone wire) is also bad, thats needs to be repaired or replaced. Call (775)358-2922 ask for Randy. Thanks.

I have a flag says default tamper certificate


You should send the terminal for repair service.
The tamper is normally a security warning that the terminal shows for some events like someone who tryied to force it or similar.
You should contact your repair service desk and send it for repair for further and better check for the cause of the tamper

Our VX 57x Dual Comm terminal was dropped and ever since has been flashing Tamper Default Certificate. How can I clear the Tamper warning.


When unit is dropped, the sensors inside may have been disturbed and the plastic might need replacing. Then tamper removal software is needed to set the unit back to factory specs. Call Frank 775-338-6634
