Eye scans for Singaporeans and permanent residents are being trialled at Woodlands and Tuas checkpoints, and Tanah Merah Ferry Terminal, as part of plans by Singapore's border agency to better secure the borders.

The trial, conducted at selected counters at the three checkpoints, involves officers scanning travellers' iris images in addition to fingerprint verification, an Immigration and Checkpoints Authority (ICA) spokesman told The Straits Times.
