The short version.
The currency is the Singapore dollar. Cards work almost everywhere a visitor spends, contactless is normal, and the places that still prefer cash are the ones worth going to: the hawker stalls, the older coffee shops, the market vendors. Carrying a modest amount of cash for food and keeping a card for everything else is the shape that works.
What this page does not publish, and why that is a result.
No source in this cluster research register states a cash declaration threshold for Singapore. The words do not appear on the entry advice this cluster cites. Singapore does operate a cross-border currency reporting regime, and this page publishes no figure for it, because publishing a number nobody here can check is worse than saying plainly that the number is not in evidence.
That matters more than it sounds, because a neighboring country's entry advice does carry a figure and a penalty, and it would be an easy sentence to carry across a border that people cross by bus. If you are moving a significant sum, take the question to Singapore Customs or to the Immigration and Checkpoints Authority rather than to a travel page.
Money changers are part of how this city works.
Licensed money changers in the shopping centers and the older streets are an ordinary part of the retail landscape here rather than a last resort, and rates in them are generally better than at an airport counter. Two sensible habits that need no source: compare a couple of counters before committing, because they sit next to each other for exactly that reason, and count what you are handed before leaving the window.
Hawker centers, and why cash still matters.
Many stalls now take digital payment and some take nothing else, but the assumption that every stall takes a card is the one that leaves you standing at a counter with nothing to hand over. Small notes are the useful denomination. The food guide in this cluster goes into how hawker centers work, including the tray return rules that are now enforced.
The scam warning is in the safety advice, and it is about your phone.
The UK Foreign, Commonwealth and Development Office safety advice records that online scams and phone scams are common in Singapore. That is not a warning about pickpockets, and it is worth reading as what it is: the threat to a visitor's money here is far more likely to arrive as a message than as a hand in a pocket.
The practical reading is the ordinary one. Nobody legitimate asks for a transfer or a code over the phone. A message that creates urgency about a payment is the shape the problem takes. And the same advice records that violent crime and theft are rare in Singapore, which is the context for all of this: the risk profile here is unusual, and it is unusual in the direction of your screen rather than your pocket.
Tipping, and what a service charge means.
Tipping is not the custom here in the way it is in the United States. Many restaurants add a service charge and a goods and services tax to the bill, and the price on a menu is often not the price you pay, so it is worth looking at the small print at the foot of a menu before ordering. Hawker stalls charge what the sign says and expect nothing on top.
Before you go.
Tell your bank you are traveling. Bring a second card kept somewhere other than the first. Draw a modest amount of cash for food rather than for everything. And if a message arrives asking you to move money quickly, treat it as the thing the safety advice says it is.
