This emoji covers both the concept of an online 'digital identity' and a real-world 'ID card.' It symbolically represents situations requiring website sign-ups or identity verification.

In modern society, personal identity is very important. This emoji symbolizes more than just identification; it represents all ways of proving and expressing 'oneself.' It can also be linked to the K-pop fandom phenomenon where 'photocards (poca)' of favorite idols are treated like ID cards.
