In a move to enhance security, all Singaporeans passing through the Woodlands Checkpoint by bus or on foot are now required to scan their thumbprints using biometric technology. SMU Assistant Professor of Strategic Management (Education) Terence Fan said that the move towards biometric technology enhances border protection by matching the identity of the person holding the passport to the biometric details embedded within the document. But travellers may be inconvenienced if the system does not accommodate people whose fingerprints may be hard to read. He said: "I myself have sensitive skin which peels off easily and this sometimes gets me into 'trouble' if only thumbprint scanning is done. In some countries, all 10 fingers are scanned."
