identification card

An identification card is an important card that proves a person's identity. It's an official document, like a driver's license or resident registration card, that verifies your identity.

These days, digital identification cards are also widely used. You can store your ID card on your smartphone and easily show it when needed. It's essential for verifying your identity at banks or government offices.

Identification cards serve as official proof of a person's identity in modern society, and their importance has grown in our globalized world. There are also internationally recognized IDs, such as international student cards or passports.

Each country has its own unique identification culture, with its own specific ID system, like Korea's resident registration card. Recently, digital identification cards using blockchain technology have emerged as a new trend.
