What records may an ATM retain?¶

An ATM can retain an electronic journal, dispense and fault events and CCTV in addition to the issuer's account record.

Machine records describe physical processing¶

Journals may show terminal, location, masked card, time, transaction type, amount requested, authorisation and dispense result. They can include PIN failures, card retention, balance enquiries, cash jams, partial dispense and reversals. Service logs may explain a disputed cash result.

The issuer records account authorisation and impact; the operator records terminal behaviour. Their references can link the two.

Preserve volatile sources promptly¶

Record terminal ID, location, time zone and clock accuracy, amount and reference. Obtain journal, dispense and fault data, reversal and CCTV before short retention expires.

Report issuer, terminal, cash and visual events separately, without equating debit with collection or footage with identity.
