POS receipt redaction is the removal of sensitive authentication data from a terminal slip under PCI-DSS v4.0 Req. 3.3. That clause bars storing the full track, CVV, or PIN after a sale. anonym.plus marks each value on your device, so the receipt stays readable while data is shielded.
When this applies
A terminal print shows the buyer name, masked digits, and an approval code. You strip the sensitive parts under Requirement 3.3 before it is filed.
How anonym.plus handles it
- Open the receipt in anonym.plus on your device.
- Local OCR reads a thermal or photographed print.
- The tool flags account digits, names, and codes.
- Confirm each flag on a faint image.
- Black out or swap the confirmed items.
- Save the clean copy locally.
What you need to provide
- The terminal slip (image scan, PDF).
- An operator (Redact suits a printed receipt).
- Optional batch of up to 20 files per run.

Limitations & cautions
Thermal ink fades, so OCR may struggle on an old print. Check the flags on weak images. The tool marks named fields but cannot recover smudged digits.
Frequently asked questions
What may a terminal receipt never store under Req. 3.3?
The full track data, the card verification value, and the PIN. anonym.plus also flags the visible name and account fields.
Can the tool read a faded thermal print?
Local OCR tries, but very faint images may need a clearer scan. Verify the flags on weak ones.
Is the receipt uploaded?
No. The app is fully offline, so it stays on your device.
