Octopus cards

Authorities in Hong Kong have ordered KMB, the city's largest bus operator, to investigate glitches in its fare rebate machines that gave passengers free rides on the launch day of a revised HK$2 transport subsidy scheme. Welfare Secretary Chris Sun Yuk-han stressed that the government's system functioned correctly, with any extra costs to be borne by KMB. The Transport Department demanded an immediate probe and a full report.
