How to Clear Terminal Certificates

Prerequisites

• Ensure Administrator Login is completed. For engineer mode terminals, login is default.
• Have a TF-card ready for use.

Steps to Generate and Verify Token

1. Insert the TF-card into the Terminal:
   • Place the TF-card in the designated slot on the terminal.
2. Navigate to Certificate Management:
   • Go to Settings > About POS > POS Configuration > Certificate Management.
3. Generate Token:
   • Choose Clear Certificates.
   • Select the Generate token radio button.
   • Click the Confirm button. This action generates a token file in the root path of the TF-card.
   • A notification will appear in the notification bar upon completion.
4. Send Token File to WizarPOS:
   • Transfer the token file from the TF-card to your computer.
   • Email the token file to WizarPOS for signing.
   • WizarPOS will return a signed '.sig' file.
5. Verify Token:
   • Place the '.sig' file on the TF-card, in the same location as the token file.
   • Reinsert the TF-card into the terminal.
   • Return to 'Certificate Management' and select 'Clear Certificates'.
   • Choose the 'Verify token' radio button and click 'Confirm'.
   • A notification will appear in the notification bar upon successful verification.
6. Restart and Confirm Clearance:
   • Restart the terminal.
   • Navigate to Settings > About POS > POS Configuration > Certificate Management > Certificate List.
   • Verify that all certificates have been cleared.

Important Notes

• These steps must be performed with administrative privileges.
• Ensure that the TF-card is correctly inserted and recognized by the terminal before proceeding with each step.
