Sensing By Galvanic Contacts TRIZ Cases

Electromagnetic noise inside the card reader blocks magnetic strip reads and skimmers, forcing secure chip-based transactions.

Firmware limits card insertion so the chip can be read while the magnetic strip never reaches the read head, blocking skimmers without hardware changes.

Firmware limits card insertion so the chip can be read while the magnetic strip stays beyond the read head, blocking skimmer access without hardware changes.

A connector-board breakage circuit detects disconnection or short circuits near the IC card opening, preserving tamper protection.

Integrating a movable magnetic head within a smart card connector opening reduces device thickness while maintaining dual-format reading accuracy.

Temperature-resistant security domes bond to electronic cards via adhesive, eliminating manual soldering stress and improving installation precision.

An integrated circuit in a smart card generates dedicated encryption keys to protect identification data against fraud during online transactions.

A tongue component with an electrical contact inserts into a card reader slot to verify the presence of foreign objects before transactions.

A card reader uses a breakage detection circuit pattern to surround a data signal circuit pattern.

Conductive guide portion discharges static electricity from cards, while silicone rubber cover absorbs impact energy to prevent physical damage.

A dual-frequency RFID circuit uses low-pass filters to manage tamper-evident loop state detection.

A handheld optical reader uses sequential multi-directional lighting to capture and synthesize symbol outlines from different illumination angles.

Equipotential circuitry maintains zero voltage difference across signal conductors, preventing illicit information retrieval through voltage tapping.

A payment terminal processing unit applies non-standard signals to contact lines and measures electrical responses.

Segmented conductors in a protective wire grid trigger a disabling circuit that erases encryption keys upon detecting tampering attempts.
