A CMT Chicago charge on your credit or debit card statement is a Chicago taxicab fare processed through Creative Mobile Technologies, the company that provides the card readers and payment systems installed in licensed Chicago cabs. If the charge is on your statement, it almost certainly means you, or someone authorized to use your card, paid for a taxi ride in Chicago.
Why It Shows Up as CMT Instead of the Cab Company
Creative Mobile Technologies, LLC, founded in 2005, supplies the rear-seat touchscreens, card readers, and point-of-sale equipment used in taxis in Chicago and many other cities.1CMT Group.

Approved Credit Card Processing Equipment for Taxis When you tap, swipe, or insert a card in the back seat of a Chicago cab, the payment routes through CMT’s system, so CMT appears on the statement instead of the taxi company or the driver.
How the Charge Reads on Your Statement
Billing descriptors on card statements are short text strings, typically limited to about 20 to 25 characters, and can include a merchant name, city, state abbreviation, and a reference code.3Stripe. Billing Descriptors A Chicago cab fare through CMT will usually show some combination of “CMT,” “Chicago,” and “IL,” often followed by a string of numbers. That numeric string is not a second charge. It is an internal payment reference for the specific ride.
Card issuers truncate and format descriptors differently, so one person might see “CMT CHICAGO IL” with a trailing number and another might see a shorter version. The underlying transaction is the same.

If You Don’t Recognize the Charge
Most unfamiliar CMT charges turn out to be rides the cardholder simply didn’t connect to the name “CMT.” Check the date and amount against your calendar, travel history, or the movements of anyone else authorized to use your card. Airport arrivals, late-night rides home, and short business trips are common culprits.
To confirm the details, you can request a receipt through Curb, CMT’s consumer-facing brand. The online request form asks for your name, email, phone number, the approximate drop-off date and time, the amount charged, and the first five and last four digits of the card used.8Curb. Customer Receipt Request Receipts are not sent automatically at the end of a ride, so this step is often necessary.

How to Dispute the Charge
If you confirm the charge is not yours, or you believe you were overcharged, you can dispute it with your card issuer. Under the Fair Credit Billing Act, notify your issuer in writing within 60 days of the statement date on which the charge appeared. The issuer must acknowledge the dispute within 30 days and complete its investigation within two billing cycles, and you are not required to pay the disputed amount while the investigation is pending.10Consumer Financial Protection Bureau. How Do I Dispute a Charge on My Credit Card Bill
If the issue is a fare dispute rather than an unauthorized charge, for example a driver demanding a flat rate above the metered fare, you can also file a complaint with the city. Chicago’s Department of Business Affairs and Consumer Protection investigates taxi fare complaints, which you can submit by calling 3-1-1 or through the city’s online feedback portal.11City of Chicago.

One boundary worth noting: CMT’s Chicago descriptor is specific to licensed Chicago taxicabs. Rides taken through app-based rideshare services or taxis in other cities will not appear this way, even if CMT operates in those markets, because those transactions carry different descriptors.
