What payment evidence may exist on a computer?¶

A computer can contain payment evidence in browsers, documents, communications, credentials, wallet software and external-device history even where no banking application is installed.

Different artefacts reveal different stages¶

History, cookies, sessions and downloads may show access and exports. Email, messages, invoices, spreadsheets and receipts can explain instructions and fund mapping. Password managers and authentication tools can link accounts. Wallet files, extensions, hashes and hardware connections can support cryptocurrency analysis; remote-access software can identify another access route.

Attribute artefacts to a user and time¶

Preserve user profiles, timestamps, browser data, applications, downloads and attached devices. Files can be old, synchronised, copied or created under another profile, and live wallets should not be opened casually.

Compare with provider sessions, transaction times and endpoint identifiers. Report presence, account access and transaction participation separately.
