Bank mandate form redaction is the removal of banking data from a salary payment form. UK GDPR and the DPA 2018 set how such financial data may be handled, overseen by the ICO. anonym.plus marks sort codes and account numbers on your device, so the form stays clear while the data goes.
When this applies
A salary mandate lists a worker's sort code and account number in one place. You must shield those before the page moves to a bureau or a shared folder.
How anonym.plus handles it
- Open the mandate in anonym.plus on your device.
- Local OCR reads a scanned, signed page.
- The tool flags sort codes, account numbers, and the name.
- Apply Mask to keep only the last digits, or Replace.
- Confirm no full value remains anywhere.
- Save the clean form locally.
What you need to provide
- The mandate (PDF, DOCX, or scan).
- The Mask operator set to keep the last few digits.
- Optional allow-list for the bank name.

Limitations & cautions
Payroll still needs the full sort code and account to pay the worker. Keep your source and redact only a shared copy. The tool masks what it detects; check faint scans before you share.
Frequently asked questions
How much of an account number may remain?
A common practice keeps only the last few digits. anonym.plus masks the rest, including the sort code, in one pass across the page.
Can it read a scanned mandate?
Yes. Local OCR reads the image, then masks the sort code and account data. Verify faint scans.
Is the mandate uploaded?
No. The app is fully offline, so financial data never leaves your device.
