where Can I Find the CCV Security Code?
Some cards, for example MasterCard and Visa, have a three-digit CCV printed on
the signature panel on the reverse side of the card. Other numbers may precede the
CCV. The last three digits on the signature panel are the CCV.
Other cards, for example American Express, have a four-digit CCV on the front of the
card, above the account number.
Some cards do not have a CCV.
Should I Save CCV Security Codes?
No. It is prohibited to store the CCV codes. They must remain secret. You must not
write them down or save them electronically. Doing so might lead to heavy penalties.
Manual Authorisations and CCV
If your terminal is not functioning at all, you can revert to a manual imprinter. When
seeking authorisation for a credit card transaction above the floor limit, be sure to
provide the CCV number if available.
