4-Digit PIN Compatibility for 6-Digit Terminals When a cardholder sets a 4-digit PIN, our system automatically enables support for terminals that require 6-digit PINs. No action is required from cardholders—this feature works automatically for all cards. Cardholders simply enter their 4-digit PIN as usual at terminals that accept 4 digits. If a Singaporean cardholder encounters a terminal that requires a 6-digit PIN, they only need to add 00 after the 4-digit PIN. Example: If the PIN is 1314, they enter 131400.
