In Korea, the use of electronic signatures is not yet widespread. Instead, it is common practice to rely on a corporate seal registered (법인인감) with the court for various transactions, including the drafting of important contracts and visits to financial institutions. When utilizing a corporate seal, you will be requested to bring the most recently issued seal certificate (법인인감증명서) to verify its registration status.
Above is a picture of the company seal (법인인감), seal card (법인인감카드), and the seal certificate (법인인감증명서) for your understanding. Hope it helps.
Kindly find the attached image displaying the company seal (법인인감), seal card (법인인감카드), and the seal certificate (법인인감증명서) for your reference.
