The Go Card is a smart card used for public transportation in various regions, allowing users to travel on buses, trains, and ferries. It simplifies the payment process by enabling users to load funds onto the card, which can then be tapped on card readers when boarding or exiting vehicles. In addition to transportation, the Go Card may offer discounts for frequent travelers and can be recharged online or at designated locations. This convenient system helps reduce the need for cash and speeds up the boarding process, making public transport more efficient for everyone.
