You may receive an SMS notification, upon adding a new card, where there is a charge of SGD 1.00 or RM 1.00 on your card. This is a small authorisation charge, which will be deducted from your card as a one-time charge. This is to verify that your card and account are both active.
Fret not, the amount will be refunded to you automatically by the bank within 7 to 14 working days. As this charge is processed by the bank, please contact your card issuer to check on the refund status.
