Regulations introduced to protect the transfer of personal data within and between different organisations. Remember that every time you apply for a store loyalty card, credit facility or magazine subscription, you are handing over substantial amounts of personal data for organisations to trade in. Whilst this data may enable them to make special offers which “may be of use to you”, it also means more opportunity to sell you products or services you would not otherwise have bought. If you are not the kind of person to say no easily, make sure you always tick the “no marketing material” box.
