6 SECURITY RECOMMENDATIONS
Security features are integrated at all levels of the VALINA
design, from the external housing to the “system-on-chip”
at the heart of the terminal. To combat fraud from external
sources, regular visual checks are essential.
INTEGRATORS
Integrators must implement appropriate procedures to guaran-
tee that every installation on the field is checked regularly.
The purpose of the checks is to make sure that:
• no camera has been set up to track cardholder activity.
• no skimming device has been attached.
• no foreign object is present in either of the card-readers.
NOTE
If anything suspect is found in the chipcard reader, or if
the VALINA is displaying a “tampered” warning message,
the integrator must:
1. Disconnect the terminal from the power source.
2. Alert the police or computer crime unit and provide
them with any requested elements for investigation.
3. Alert the acquirer with precise details on location
and situation.
4. Alert the regulator if appropriate.
MERCHANTS
For security reasons, merchants are advised to check their
VALINA every working day and make sure that:
• there is no sign of unusual cables connected anywhere
on the terminal.
• there is no foreign object in either of the card-readers.
• the terminal is not displaying any warning message.
• the housing is not visibly damaged.
• the terminal serial number (on the label) corresponds
to the inventory.
