Technical specifications for the Identiv SCR3500A define it as an ultra-compact, folding smart card reader designed for ISO 7816 Class A, B, and C contact cards. The device utilizes the Identiv STC II chipset, providing a silicon-level interface for CAC, PIV, and SIPR token access. Material analysis confirms gold-plated electrical contact pins for corrosion resistance within the SmartFold hinge mechanism.
Performance metrics indicate full CCID compliance, ensuring driverless "plug-and-play" operation across Windows, macOS, and Linux kernels. Unlike biometric scanners, this device is strictly a contact-based reader for chip-integrated cards, supporting T=0 and T=1 protocols as well as EMV 2011 Ver 4.3 standards.
- Form Factor: Folding USB-A.
- Protocol Support: ISO 7816, CCID, EMV L1.
- Operating Systems: Windows, macOS, Linux (native kernel support).
Mechanical auditing identifies the internal ribbon cable as a potential fatigue point after high-cycle folding operations. Operational data suggests a specific handshake sequence: the USB connector should be seated for approximately 2 seconds prior to card insertion to ensure the PC/SC daemon successfully polls the Answer To Reset (ATR).
If your security requirements involve biometric authentication rather than physical smart card validation, the ARCANITE USB Fingerprint Reader provides a compatible biometric alternative for Windows Hello environments.
This specialized folding unit is categorized within the usb fingerprint readers repository as a legacy-compatible token interface.
