Do not share or disclose One-Time Passwords received with any other party.

Important tips to avoid ATM and CRM thefts / scams / card skimming

If any unusual devices are observed, please avoid using the ATM/CRM and inform any security personnel or the Contact Centre on +94 11 2353353 immediately.
  • It is advised to cover the number pad using your free hand when entering the PIN so that the PIN will not be visible to any other party in the vicinity. Do not share or disclose the PIN with any other party.
  • Avoid using an ATM/CRM when other people are around and never rely on the help of strangers to operate the device, specially to deposit/withdraw cash or to retrieve a card which has been captured by the device. Instead, get in touch with the Contact Centre for assistance. 
  • The cardholder should report a card that has been captured by the device immediately to the Bank. It is advised not to leave the ATM/CRM location, but as a prudent measure call the Contact Centre from the ATM/CRM location where the card was captured.

  • Perform online purchases from companies that have a good sale history/reviews and with satisfactory terms and conditions/policies. Do not provide any information which is not relevant to the purchase. Ideally the website should have an option to confirm or decline an order before making the payment.
