The short answer
CSC ServiceWorks operates the coin-and-card laundry machines in apartment buildings, dorms, and laundromats — plus many gas-station air pumps. A small CSC charge is almost always the washing machine in your building.
Why it shows up like this
Buildings don't run their own laundry payments; they contract operators like CSC ServiceWorks, whose name goes on the card charge. Small amounts a few dollars at a time, sometimes several on one day, are a laundry-day signature.
Don’t recognize it? You might still
- You tap a card at the machine and never think of it as a 'purchase'.
- Charges can batch and post days later, sometimes on the same day as each other.
- A roommate or family member doing laundry with a shared card produces the same pattern.
What to do, in order
- Count the loads Multiple small same-day charges = wash cycles plus dryer cycles.
- Check the app balance if you use one CSC's mobile payment app (and refill cards) generate the same descriptor for top-ups.
- Request refunds through CSC directly Machine ate your money? CSC has a self-service refund request tied to the machine's ID.
Quick questions
I don't use coin laundry. Why is CSC charging me?
Check for air/vacuum machines at gas stations — CSC runs many of those too. Otherwise, ask who else has a card on your account, then dispute.
