Abstract
A financial transaction card 2, such as a check guarantee and/or credit card includes a tagging element 4 of a high permeability, low coercivity magnetic material, such as Ni Fe. The tagging element 4 is arranged in magnetic communication with a magnetic stripe 10 of relatively hard magnetic material or in a region of the card 2 used to record identifying data, such as user details, so as to be deactivated when the user details are recorded on the card 2. The provision of the element 4 enables card blanks to be monitored by an electronic article surveillance system during manufacture or prior to issue.
