I support the idea of a physical ID card, as is shown on the profile when paying the citizenship fee. I'd like to suggest that Parliament issue Smart Cards, as they are inexpensive and could make for easier citizens/residents interaction with Asgardia online, with the use of cryptographic certificates just,  like Estonia's national and eResidency programme (https://e-estonia.com/solutions/e-identity/e-residency/). It would allow for secure identity validation, which could be used for eGovernment, secure emails, and as a password replacement for access to the website via SSL client certificates. If interested, I'm happy to explain benefits and technical implementation details outside of this forum environment.
