Common questions
What does a scratched or resurfaced signature panel indicate to an examiner?+
A genuine tamper-evident panel is designed to show visible damage, such as revealing hidden VOID text or a disrupted background pattern, if someone attempts to remove and rewrite the signature or alter the panel. Damage of this kind is a strong indicator the card has been physically altered rather than used as issued.
Why is the CVV2 printed on the signature panel rather than embossed with the card number?+
Keeping the CVV2 as flat print separate from the embossed number means it is not captured by an old-style manual card imprinter or by devices that read only the embossed digits, and it is also not encoded on the magnetic stripe, reducing the ways it can be copied compared with the primary account number.
