2When this plan starts
Any one of these, suspected or confirmed.
- -Our acquirer, processor or a card brand tells us that cards used with us turned up in fraud.
- -A customer reports fraud on a card they recently used with us.
- -A computer or account used for card payments shows a login, program or change nobody on staff made.
- -Card numbers turn up where they should not be: an email, a spreadsheet, a photo, a note.
- -A card terminal looks tampered with, has a new overlay or cable, or its serial number is not on our device list.
- -Our payment-page monitoring alerts on a script or header change nobody made.
3First steps: contain without destroying evidence
- 01Stop taking cards on the affected system and switch to the fallback in section 5.
- 02Cut the affected system off from the internet: unplug its network cable or turn off its Wi-Fi. Do not switch it off, restart or reboot it.
- 03Do not log in to it, and do not change its passwords from it. Never log in with an admin account.
- 04List every part that may be affected: computers, terminals, logs, databases, card-reader overlays.
- 05Write down every action: date and time (UTC if you can), who did it and exactly what was done.
- 06Keep all evidence, the devices themselves and their logs. Do not wipe, reinstall or throw anything away.
- 07If card numbers turn up where they should not be: find where they came from, check whether a security code is stored with them, retrieve or securely delete them, and close the gap.
- 08Set a suspect terminal aside untouched, note its serial number, and keep it until the acquirer or processor says what to do with it.
- 09Ask the web host, store platform or cloud provider in writing to keep their logs and system images.
4Who we tell, in this order
- 01Call the incident lead on the 24/7 number in section 1.
- 02Call our acquirer and our payment processor straight away. Ask what they need from us and by when.
- 03Visa: the event must reach Visa within 3 calendar days of the first reasonable suspicion. Ask the acquirer whether they report it or we do.
- 04American Express, if we accept it: tell American Express within 72 hours of finding a data incident.
- 05Mastercard, Discover and other brands: follow what the acquirer tells us.
- 06Our lawyer, about any duty to tell customers or regulators.
- 07Law enforcement: local police, or in the US the Secret Service field office.
- 08Our cyber insurer, if we have one.
- 09The terminal maker or POS reseller, if the cause looks like a flaw in their equipment.
- 10The shopping-cart or store platform vendor, if the cause looks like a flaw in their software.
5Keeping the business running
How we keep taking payments
Cash only at the counter, online orders paused, until the acquirer clears a replacement terminal.
Data backups: where they are, who restores them
Orders and customer list live in the store platform; the bookkeeping file is backed up each night to cloud storage. The owner restores it.
Critical systems this plan covers
- -Office computer used for the processor's online dashboard
- -Router and Wi-Fi
- -Card terminal at the counter (make, model, serial number)
- -Online store and its payment page

7Card-brand procedures
From the brands' own documents, read 2026-10-22. Brands update these; check the current version.
Visa
What To Do If Compromised, version 10.0 (effective 25 June 2026). The event reaches Visa within 3 calendar days of the first reasonable suspicion, and an incident report goes to Visa and the acquirer within 3 calendar days after that. If we cannot reach our acquirer, Visa's North America contact is USFraudControl@visa.com; Visa's Risk Operations Center takes emergency calls 24/7 on 1-844-847-2106 (toll free).
American Express
Data Security Operating Policy, section 3 (Data Incidents): notice to American Express within 72 hours of discovery, a thorough investigation, and every affected card number sent to American Express promptly.
Mastercard, Discover, others
Our acquirer will tell us their procedure. Ask for it when we call.
Forensic investigator
A card brand may require a PCI Forensic Investigator (PFI). Once Visa requires one, we sign with a PFI within 5 business days. The PFI cannot be a firm that worked for us in the past 3 years, for example as our QSA or consultant. The PCI Security Standards Council lists PFIs on its website.
