Sensing Record Carriers TRIZ Cases
- 2D Code Position Detection Pattern Displacement for Curved Surface Recognition
Displacing position detection patterns in a 2D code avoids unrecognizable regions on curled surfaces, ensuring reliable decoding accuracy.
- Tamper-Evident RFID Tag With Melted Boss Attachment
Melted protrusions form an integral boss over the RFID tag, resolving the trade-off between easy attachment and tamper-proof reliability.
- Wireless Product Guidance System for Retail Information Accuracy
Portable devices parse wireless signals from product transmitters to retrieve and display real-time inventory data.
- Stripline Magnetic Writing of Dynamic Data in Static Regions
Dual-coercivity magnetic stripes allow stripline writing of dynamic data without disturbing static information, overcoming thermal instability limits.
- Electronic Transaction Device Simulated Magnetic Field Security
An electronic transaction device generates analog waveforms to simulate a magnetic field for standard readers.
- POS Terminal Dual Reader Controller Dynamic Mode Management
A dual reader controller dynamically adjusts card reader modes based on workflow states to optimize power usage.
- Decoupled RFID Tag With Segmented Near-Field and Far-Field Antenna
Segmenting the RFID device into a universal near-field tag and an intermediary far-field antenna resolves impedance mismatch across varying product dielectrics.
