# Generic ID

{% hint style="info" %}
We do support eID cards (ID-1 format) issued by countries that include a Machine Readable Zone (MRZ) on the back, comply with ICAO Doc 9303, and contain a contactless chip (ISO/IEC 14443 / NFC). This feature is available in the "Enrollment Flow" and "NFC / Reading Flow" using the document type GENERIC\_ID or MRZ (when scanning only the back side). If a country is not supported, the NFC reading step is skipped according to the SDK's default configuration.\
If you believe an eID card complies with the standard but the SDK still skips the NFC reading step, please contact us.

{% hint style="info" %}
The validity section below includes security-related data. Consumers should evaluate this data using the [**verification.reading**](/docs/kyc/uqudo-sdk/sdk-result/data-structure/verification-object.md) object, which provides the canonical source for implementing business-specific validation and verification logic.
