The EZ-Link card is a rechargeable contactless smart card and electronic money system that is primarily used as a payment method for public transport such as bus and rail lines in Singapore. A standard EZ-Link card is a credit-card sized stored-value contact-less smart-card that comes in a variety of colours, as well as limited edition designs. It is sold by SimplyGo Pte Ltd, a merged entity of TransitLink and EZ-Link since 2024, a subsidiary of the Land Transport Authority (LTA), and can be used on travel modes across Singapore, including the Mass Rapid Transit (MRT), the Light Rail Transit (LRT), public buses which are operated by SBS Transit, SMRT Buses, Tower Transit Singapore and Go-Ahead Singapore, as well as the Sentosa Express.
Established in 2001, the first generation of the card was based on the Sony FeliCa smart card technology and was promoted as the means for speedier boarding times on the city-state's bus and rail services. It had a monopoly on public transportation fare payments in Singapore until September 2009, when the NETS FlashPay card, which had a monopoly over Electronic Road Pricing toll payments, entered the market for transportation payments (and vice versa). EZ-Link cards are distributed and managed by EZ-Link Pte.
