Singapore’s public transport system is often praised as one of the most efficient in the world. But hidden beneath this reputation is a lesser-known problem that quietly drains money from unsuspecting commuters — including locals, tourists, and even students.
It involves the SimplyGo contactless payment system, and it could be costing you money without your consent.
🎫 How SimplyGo Works — and Where It Goes Wrong
The SimplyGo system, operated by TransitLink (a subsidiary of the Land Transport Authority), allows commuters to tap in and out of MRT stations and buses using contactless credit or debit cards (Visa, Mastercard, NETS) or mobile wallets (Apple Pay, Google Pay, etc.).
You’re told to “tap in and out with the same card” — simple enough, right?
But what they don’t clearly tell you is this:
🛑 If you tap your wallet or phone case with multiple cards inside, the system may scan the wrong card — or even multiple cards. You won’t even notice it happening. And when it does, you get charged.
😱 Real-World Example
Let’s say you have both a DBS PayNow-linked card and a Mastercard in your wallet.You tap your wallet at the bus reader.
You assume it uses your PayNow card.
But the system reads the Mastercard instead.
Now:
- You’re charged a full fare (or an incorrect one).
- The trip may be logged as incomplete.
- You don’t even see it unless you check your credit card statement later.
- And by then, it may be too late.
⏳ The 90-Day Refund Trap
If you find a suspicious charge, here’s what you need to do:
- Register that specific card on the SimplyGo app or TransitLink portal.
- Find the transaction.
- File a manual claim — and you must do it within 90 days of the charge.
If you miss that deadline?
💸 Your money is gone for good. No refund. No reversal. No recourse.
And here’s the troubling part:
There is a 90-day limit to which you can claim a scam or unauthorized scan of your credit or debit card by Singapore’s SimplyGo transit card readers.
These readers are installed on every MRT gate and public bus, and they are designed to pick up any nearby bank card or NFC-enabled card.
If you do not physically remove and tap the card you want, the system might scan any other card in your wallet, leading to accidental — and often unnoticed — deductions.
TransitLink does not publicly disclose what happens to money that remains unclaimed after 90 days. That’s a serious lack of transparency.
It Was Even Reported in the Media
This issue is not new. In fact, The Straits Times highlighted the problem as early as last year in a report titled “Refunds made for two out of every 100,000 trips on SimplyGo”.
The article confirmed that only a tiny fraction of commuters seek refunds — not because errors are rare, but because most people:
- Don’t know a wrong card was charged,
- Aren’t registered with the app, or
- Miss the 90-day deadline.
As usual, the report was met with excuses from authorities on why the problem “cannot be solved,” rather than meaningful action to fix the design flaw or protect users.
This further proves that the system is aware of the issue — but hasn’t addressed it in a way that protects commuters.
🕵️♂️ Why This Feels Like a Legal Scam
Let’s be blunt.
This system:
- Allows charges without explicit authorization.
- Fails to alert users to possible scanning errors or card clashes.
- Places all responsibility on the user to detect and dispute the error.
- Refuses refunds after 90 days — even if the charge was clearly invalid.
This isn’t just bad design — it’s a systemic loophole that could be quietly profiting from your mistake.
Imagine if thousands of people are wrongly charged just $1 to $3 a day and fail to reclaim it in time. That’s millions annually in unrefunded money.
👎 Tourists Are Even More Vulnerable
Tourists who tap their foreign cards may get hit with:
- Extra bank fees
- Untrackable full fares
- Zero knowledge of how to check or reclaim their money
And most will never even know they were charged wrongly.
✅ How to Protect Yourself
- Use only one card or phone for tapping.
Avoid tapping wallets or phone cases with multiple NFC-enabled cards inside. - Register all your payment cards on the SimplyGo app if you use them for transit.
- Check your transaction history regularly.
Especially if you notice strange charges in your bank statements. - Act fast — you only have 90 days to dispute any errors.
- Spread the word.
Tell friends, family, tourists, and especially seniors or students who may be more easily affected.
📢 Call for Change
This is a flawed and unfair system that needs to be fixed. Some suggestions:
- TransitLink should require clear warnings at all gantries about card clash risks.
- Automatic alerts should be sent when an incomplete trip is detected.
- Refund deadlines should be extended or eliminated for clear errors.
- MAS (Monetary Authority of Singapore) should review the legality of unauthorized contactless charges.
- Transparency is needed: Where does the money from unclaimed fare errors go?
🗣️ Final Thoughts
Singapore’s transport system is modern — but this hidden problem shows how technology, when poorly managed, can quietly exploit users.
If you’ve ever used a contactless card to board a bus or MRT — check your bank statement today. You might just discover a charge you never meant to make.
