What to Do If a Vending Machine Rejects Your Money
A calm troubleshooting sequence for rejected coins, notes, IC cards, sold-out buttons and change-return problems in Japan.
A rejected payment usually has a simple cause: the denomination is unsupported, the cash is damaged, the IC balance is low, the item is sold out or the machine has not completed the previous step.
What you will actually find
A coin may drop directly into the return tray, while a note can be pushed back out. On an IC machine, no confirmation sound or an error light can indicate insufficient balance or an unsupported card. A dark product button often means that the item cannot currently be purchased.
Practical advice
Pause before trying again. Retrieve the money, check the accepted-denomination icons, smooth a note, confirm the item and try once more. If payment appears to have been taken without a product, photograph the machine number and operator contact panel and seek venue staff help.
Troubleshoot in order
- Check the coin return, note slot and change tray.
- Confirm the denomination and payment mark are supported.
- Check that the item button is available and the price is covered.
- Try one clean coin, note or IC card once more.
- If money is retained, record the machine ID, time, location and operator contact.
What not to assume
Do not hit, shake, tilt or pry open a machine. Avoid repeatedly inserting the same rejected cash; move to another payment method or machine when possible.
