What is the currency in Singapore?

The currency in Singapore is the Singapore Dollar (SGD). Notes come in denominations of $2, $5, $10, $50, $100, and $1,000, while coins are available in 5, 10, 20, and 50 cents, and $1. Credit cards are widely accepted in hotels, restaurants, and shopping centres, though it's advisable to carry some cash for small purchases at hawker centres and local shops.  

Currency exchange services are readily available throughout the city, with competitive rates typically found at money changers in shopping areas rather than at hotels or the airport.
