Model and source
R502-CL · official CheckID public product source. Source status: SOURCE_BACKED.
Source-backed hardware
Contact smart card · ISO 7816; Contactless · ISO 14443 A/B; USB 2.0 CCID host interface.
Middleware boundary
PC/SC · WINSCARD / CT-API; Driver / firmware security controls; Multi-OS host support as published.
CheckID integration
SDK/API cross-link. Device capability does not imply every verification method is supported.
Publication rule
No CPU/OS/interface/certification is added beyond the matrix/datasheet. Compatibility is tied to tested configuration or source version.
Lifecycle and limitations
Where EOL, firmware compatibility or tested OS is not sourced, records a publication limitation rather than inferring it.
