The security sticker and method for banking cards includes security stickers that provide protection of information displayed on cards, by allowing users to apply an adhesive backed, tamper evident, camouflaged sticker over any information the user wishes to protect. Different embodiments of the security stickers are provided for users having different kinds of banking cards. An adhesive sticker kit for banking cards includes at least two adhesive stickers to cover the front and back of the bank account numbers displayed on the cards, at least one sticker of different size covering the security code of the cards, another sticker advising to “Check Photo ID” of user, and at least one sticker displays account information protection advisory statements. The security sticker substrate has a top layer that will crack if someone attempts to remove the sticker from the card, thereby alerting the cardholder that someone has tampered with the banking card.
