# Choose CheckID resources by task and model

Separate data reading, document checks, holder comparison and the selected device.

Conceptual and implementation-planning guidance

## Separate workflow tasks

A request to read an identity card may mean data extraction alone or may include document and holder checks. State each required output. A data read does not establish completion of every identity step.

The CheckID brochure covers NFC chip reading, personal data, a portrait and integration options. Chip reading and a call to an external verification service are distinct tasks with separate prerequisites.



## Select the device and matching documentation

Look up the exact model, then read its datasheet and operating guide. The collection includes multiple CheckID-SR resources and other readers; a filename date is a comparison hint, not confirmation of current support.

The reviewed CheckID-SR datasheet describes USB connectivity, contactless reading and two-sided scanning. Check the receiving application, power, installation space and project operating system before selection.



## Test in the intended environment

Use authorised test documents or data. Record actions, returned fields, output formats and error messages. Test from the device into the business screen rather than relying only on a standalone demo.

Include unreadable cards, interrupted actions and user retries. Operations should be able to distinguish device, application and service-connectivity problems.



## Hand over traceable information

Keep the model, software version, applicable resources and support contacts in the project record. Incident reports should include reproduction steps and messages while limiting personal data in shared material.

Retest affected steps after replacing equipment or upgrading an application. Confirm compatibility using documentation and results from the intended environment.
