licen check (查牌)
DESCRIPTION
LicenCheck is a free service that provides a searchable interface to data provided by the Hong Kong Food and Environmental Hygiene Department. Hong Kong requires operating restaurants to maintain valid licenses. But in Hong Kong's fast-moving economy it can be difficult to keep up with changes in restaurants and licenses. This application was designed to help the civil servants that enforce licenses and the general public that wants to validate the status of their local eateries. LicenCheck was developed by Alfred Lai, Ding Lam, Ron Tam, and Solomon Yan, students at the Institute of Vocational Education (IVE) in the Department of Multimedia and Internet Technology, with support of the IVE Cloud Innovation Center, and collaborating with Open Data Hong Kong. Further funding for this project comes from Amazon Web Services in the form of an Education Grant Award.TRANSCRIPT
