A primary account number (PAN) on a credit card is highly regulated under PCI-DSS. Storing or sharing PANs outside a PCI-compliant environment can trigger contractual penalties from card networks and trigger breach-notification obligations.
Any document containing a full PAN that is shared, archived outside scope, or attached to an email should have the PAN redacted — typically leaving only the last 4 digits visible if needed.
Every potential card number is validated using the Luhn checksum before being flagged. This dramatically reduces false positives on similar 13–19 digit strings (account references, order numbers).
Batch processing supported — handle hundreds of files at once.
Combine with Name, Email, Phone, and Address categories.
Verify detections page-by-page. Add manual masks for any handwritten card numbers.
Card numbers are permanently rasterized over.
Operational receipts and expense documentation often contain PANs that should never leave your PCI-DSS boundary. Redact them in bulk before archiving.
Yes. All major PAN formats (13, 15, 16, 19 digits) are validated via Luhn.
Not automatically — the full detection is masked. For a "last 4 visible" pattern, post-process the redacted output manually.
Luhn validation eliminates most false positives, but very occasionally a random 16-digit number passes Luhn. Studio review catches these.
