From 3rd August 2009 onwards, each Maestro/Switch card used by players to top up bingo account balances must use an added security measure called MasterCard SecureCode in order to successfully complete transactions online. This is a requirement that is geared towards making your card even more safe when used in an online environment.
Players who attempt to use Maestro/Switch cards and are not enrolled for the MasterCard SecureCode program unfortunately will have their transaction declined.
The SecureCode enhances your current Maestro/Switch card with a secret code to protect against unauthorized use of your card when you shop online at participating merchants.
It is a simple process to activate the 3D secure feature of your Maestro/Switch card by contacting your issuing bank. For more information, please visit http://www.mastercard.com/uk/personal/en/cardholderservices/securecode/index.html
