A CSI charge on a bank statement is almost always a legitimate recurring payment moving through a processor or banking-technology company whose name ended up on the descriptor instead of the business you actually paid. The two most common culprits are Computer Services, Inc., which runs the back-end platform for roughly 10 percent of U.S. banks, and CSI Spectrum, a payment processor used by gyms, YMCAs, and community rec centers.1CSI.

What the CSI Label Actually Means
If your bank is a community bank or credit union that outsources its digital plumbing to Computer Services, Inc., any automated bill payment, transfer, or scheduled loan payment run through that system can post as “CSI.” The money went to your utility, insurer, or mortgage servicer; the descriptor just names the technology company that moved it.
CSI Spectrum works similarly for fitness and recreation facilities. It handles point-of-sale swipes, monthly dues billed to a stored card, and payments made through online member portals. Join a pool or gym that uses it and your monthly charge shows up as CSI rather than the facility’s name.
Less often, a CSI charge traces back to professional software subscriptions — tax and accounting research tools, for example — or to a third-party card processor working on behalf of a smaller retailer. The pattern holds either way: CSI charges are almost always tied to a recurring authorization, even one you’ve forgotten setting up.
Identifying the Real Merchant
Start with the dollar amount. A round monthly figure like $29.99 or $14.95 usually matches a subscription. Search your email for signup or renewal confirmations dated near the charge. Most mystery charges stop being mysteries at this step.
If the amount doesn’t jog anything loose, open the transaction inside your banking app. Many banks show a merchant phone number, city, or category code below the main line. A phone number is the most useful piece — call the merchant and ask what the charge covers.
For ACH debits, the transaction detail should include a trace number that identifies the originating bank and the specific entry.3ACH Guide for Developers. ACH File Overview Your bank can use it to follow the funds. Write it down before you call customer service.
Stopping a Recurring CSI Charge You No Longer Want
If the charge is legitimate but you want it to end — you cancelled the gym, dropped the subscription, switched providers — two steps matter, and skipping either one leaves you exposed.
Cancel with the merchant first. Get written confirmation, even a brief email. Blocking a payment at the bank does not release you from a contract you signed, and the merchant can still send an unpaid balance to collections if the underlying agreement is active.
Then place a stop-payment order with your bank. Federal law gives you the right to stop any preauthorized electronic transfer by notifying the bank at least three business days before the next scheduled payment.4Office of the Law Revision Counsel. 15 US Code 1693e – Preauthorized Transfers Notice can be by phone or in writing, but if you call, the bank can require written confirmation within 14 days. Miss that written follow-up and the stop-payment order expires.5eCFR. 12 CFR 1005.10 – Preauthorized Transfers Expect a fee of roughly $15 to $35.
Disputing a CSI Charge You Never Authorized
A dispute is a different tool from a stop-payment. Use it when you never agreed to the charge or the amount is wrong. The rules split based on the account it hit.
Debit Cards and Bank Accounts
Unauthorized electronic debits are covered by Regulation E. Your notice of error has to identify the transaction, explain why you believe it’s wrong, and state the amount, and it must reach the bank within 60 days of the statement date that first showed the error.6Consumer Financial Protection Bureau. 12 CFR 1005.11 – Procedures for Resolving Errors
The bank then has 10 business days to investigate and decide. It can take up to 45 days if it credits your account provisionally within those first 10 days so you aren’t out the money during the review. Confirm the error and the provisional credit becomes permanent; find no error and the bank pulls the funds back and sends you a written explanation.
Credit Cards
Credit card disputes fall under the Fair Credit Billing Act. You have 60 days from the date the statement was sent to notify the issuer in writing, with your name, account number, the disputed amount, and the reason.7Office of the Law Revision Counsel. 15 US Code 1666 – Correction of Billing Errors While the issuer investigates, it cannot try to collect the disputed amount or report it as delinquent.
What Waiting Costs You
For debit accounts, liability for unauthorized transfers rises in tiers tied to a lost or stolen card:
- Report within 2 business days of discovering the problem: liability capped at $50.
- Report after 2 business days but within 60 days of the statement date: liability up to $500.
- Report after 60 days from the statement date: no cap on unauthorized transfers that occur after the 60-day window closes.
Even outside the lost-card scenario, ignoring an unauthorized transfer on your statement for more than 60 days strips your protection against any further unauthorized charges that follow.8Consumer Financial Protection Bureau. 12 CFR 1005.6 – Liability of Consumer for Unauthorized Transfers
Credit card liability for unauthorized charges is capped at $50 by federal law regardless of timing. But miss the 60-day window and the issuer has no duty to investigate a billing error. Practically, you eat the charge.
Don’t Dispute a Charge You Recognize
Filing a dispute for a charge you know is valid — sometimes called friendly fraud — carries real risk. Deliberately submitting a false claim to obtain a credit you aren’t owed can be prosecuted as bank fraud, which carries penalties of up to 30 years in prison and a $1,000,000 fine.9Office of the Law Revision Counsel. 18 US Code 1344 – Bank Fraud Prosecutions of consumers over small amounts are rare, but banks track dispute patterns and repeated reversed chargebacks can lead to account closure. If you recognize the charge and just want it to stop, use the stop-payment process instead.
