Sensing By Galvanic Contacts TRIZ Cases
- Card Reader EMI Shielding Against Magnetic Strip Skimming
Electromagnetic noise inside the card reader blocks magnetic strip reads and skimmers, forcing secure chip-based transactions.
- Card Reader Firmware Control to Block Magnetic Strip Skimming
Firmware limits card insertion so the chip can be read while the magnetic strip never reaches the read head, blocking skimmers without hardware changes.
- Card Reader Firmware Control for Chip-Only Skimming Protection
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.
