The industry-wide move to replace signature cards with PIN cards has started since from mid-2015. Signature will gradually be phased out as cards and terminals are upgraded. When you receive your new Chip and PIN card, you should enter a PIN when prompted, instead of signing, when making a card payment at a point of sale terminal in Malaysia.
From 1 July 2017 onwards, signature will no longer be accepted when you use your card to make a domestic payment. If you are using your card overseas, please ensure you remember the PIN for your card before leaving Malaysia. Those countries that have not yet migrated to PIN will still require that you sign for verification in order to use your card for payment. However, because your new card supports PIN for purchases, some countries may require payment to be completed with a PIN when prompted.
