To travel anywhere by bus or MRT (Mass Rapid Transit), purchase an EZ-Link card at a station or convenience store.
Swipe this contactless stored value card to get in and out of stations and on and off buses.
The fare, usually no more than a couple of dollars, is based on distance travelled. Additional value can be loaded on to the cards via machines at all MRT station or with the EZ-Link app.
Children under 7 can get a special card entitling them to free travel but proof of age is required.
