AB  - This study aims to provide DID service providers with practical guidance on how to improve DID services. As a result of studying 
the actual service of providing DID service as a mobile employee card, we found the phenomenon of unmet expectation that the intention 
of providing the service is not delivered to the service user. It can be argued that DID services are not suitable for mobile employee 
cards, where the issuer stores all the employees’ information, and it can be posited that significant service strategic planning errors lead 
to the failure of DID service proliferation. We suggest that it is necessary to rethink the service strategy from an ESG perspective, such 
as trading personal information between companies, rather than replacing the digital version of physical ID cards.
