We have recently identified an issue affecting Verifone devices following a Windows update. Some systems may display the following errors:
“Datacap Configuration Not Found or Incorrect”
or
“Transaction Not Complete – NAK error from PIN Pad”
We are actively investigating this issue with Verifone and will provide updates as they become available.
Resolution Steps:
Please ensure the Verifone PIN pad is disconnected during the uninstall/reinstall process and only reconnected once the drivers are successfully installed. To restore device functionality, please follow these steps:
1 Uninstall the Verifone drivers currently installed on the affected PC.
2 Reboot the PC to clear any residual driver conflicts.
3 Unplug the Verifone device.
4 Reinstall the Verifone drivers using the latest version available from Datacap support.
