Simjian's earliest verified self-service banking filing (filed April 9, 1959): a machine activated by coded subscriber identification that validates identity and time period, then invalidates the ID against reuse. Batiz-Lazo and Reid identify this, not a mythical 1939 patent, as the real start of the Simjian record; it underpinned the 1961 Bankograph trial at a New York City bank.

Docutel's networked Total Teller-era system patent whose depository module — envelope transport, serial numbering device, envelope stackers — is the canonical description of first/second-generation ATM deposit: a sealed envelope, serial-stamped for audit, with zero validation of contents. The deposit is a promise, verified later by a human.

The earliest video-teller ATM patent found. A customer at an unattended remote unit presses for help; a teller-assist operator answers by audio, enters the transaction on the bank-station keyboard, and switches 'a picture of the operator taken by the video camera' onto the unit's display. Filed 11 December 1973, thirty years before the interactive teller machine. Cited by the uGenius patent.

Circulation-type cash handling with mode switching (receive-only / dispense-only / both) driven by container fill levels — the operational logic that makes recycling viable without constant clerk intervention. Omron's recycling IP later merged with Hitachi's in the 2004 Hitachi-Omron Terminal Solutions JV.

Early Japanese cash-recycling patent: deposited notes are sorted by denomination into pocket sections and re-dispensed as withdrawal cash. Documents the Japanese lead (Toshiba/Hitachi/Omron/Glory) in note recycling roughly two decades before US/European deployers adopted it.

Hitachi's bill recycle module (BRM) family: auto-replenishes recycling boxes from a supply cassette only when the customer sensor shows nobody waiting, pausing if a customer approaches. Early evidence of Hitachi treating the recycler as an inventory-management system, not just a transport.

Diebold's late-1990s recycling ABM program: doubles detection, deskewing and centering of documents on a central transport that both accepts deposits (denominating and storing them) and re-dispenses them — note validation moved permanently inside the recycling path.

The foundational jitter patent: intermittent stop-start card transport during insertion/ejection so an externally mounted skimmer cannot recover a clean magnetic-stripe waveform, while the internal head reads continuously once the card is enclosed. Basis of 'jitter' anti-skimming shipped industry-wide.

Firmware-level mutual authentication between ATM components: identity-data hashing and encrypted key exchange so hardware and software components verify each other before transacting. Notable for its Brazilian inventor team — Brazil's epidemic of ATM fraud in the early 2000s made Diebold's Brazilian operation a security R&D source.

Late-stage NCR check-imaging patent: an image-based depositing ATM with dual cameras (front/rear images) that emails or web-links the acknowledgement instead of printing it. Evidence of how thoroughly the imaging core was settled by 2008 — the patentable frontier had moved to the receipt.

Nidec Sankyo's orientation-based defense: conveying the card in its short-side (width) direction with an abutting end-alignment mechanism, and detecting both longitudinal card ends to reject improper insertions that could enable illegal data acquisition — the OEM-side sibling of the 'rotate the stripe away from the skimmer' concept Diebold commercialized as ActivEdge.

Anti-internal-skimming hardware: an internal plate with pre-weakened bend/break zones blocks insertion of skimmers inside the reader throat and deliberately deforms if extracted, bricking the reader — designed against the 'deep-insert' skimmer wave that followed successful external-skimmer countermeasures.

The dominant OEM absorbing the anti-skimming stack into the reader itself: a disturbing-magnetic-field (jamming) generator built into the card reader, with soft-adhesive-filled gaps between core/bobbin/board/housing to suppress the audible vibration noise jamming coils cause.

Current state of the art on file: multiple ML models trained on terminal telemetry compete, the best is deployed, and models continuously retrain. The claims cover ATMs explicitly, among other self-service terminals. Predictive maintenance has moved from the threshold rules of the 2009-2011 filings to MLOps. Still pending as of August 2026.
