Scanning business correspondence and the GDPR: 8 rules for a secure workflow
How to digitise business mail, restrict access to data and keep control of a document from receipt to archiving.
Scanning correspondence speeds up work, but creating a PDF is not enough to make the process secure. A document passes through receipt, opening, registration, scanning, routing, storage and deletion. Personal data, financial information, trade secrets and urgent deadlines may appear at every stage.
1. Define what may be opened and scanned
Not every item should follow the same route. Confidential, private or personally addressed mail may require a separate path. Rules should be documented before the service begins so staff do not have to rely on assumptions.
2. Register before routing
The register should include at least the receipt date, sender, internal recipient, document category and status. A case number links the scan, paper original and completed actions.
3. Restrict access by role
Only people who need a document should receive access. A shared folder open to the entire company is convenient but makes accountability difficult. Roles, permission groups and periodic access reviews provide better control.
4. Use an agreed channel
Scans should not travel through private inboxes or random messaging tools. The company should designate a controlled document system, secure server or business cloud service with appropriate permissions.
5. Check quality and completeness
An unreadable scan can be as problematic as a missing document. Checks should cover page count, orientation, legibility, case allocation and whether two different items were accidentally combined.
6. Set retention periods
Working files, approved scans and paper originals may require different retention periods. These should reflect the processing purpose, legal duties and organisational rules. Once the period ends, the document should be securely deleted or destroyed.
7. Preserve an audit trail
The system should show when the document was registered, who received access and whether it was acknowledged. This history supports complaints, audits and incident analysis.
8. Prepare for incidents
A wrong recipient, missing original or unauthorised disclosure requires a rapid response. The team should know whom to notify, how to preserve evidence and how to limit the impact.
Secure digitisation is not based on one scanner or one password. It combines clear rules, limited access, quality control and a complete document history. The final design should always reflect the organisation's data and legal obligations.
Frequently asked questions
May every letter be opened and scanned?
No. The scope should follow the authorisation, client instructions and nature of the item.
Can a scan replace the paper original?
It depends on the document and applicable requirements. Some originals must still be retained.
