A newly designed South Korean passport is available for citizens starting December 21st.
The country's Foreign Ministry said that the new electronic passport is more secure.
This is because the personal information page is made of polycarbonate, a type of thermoplastic, making it more durable and heat-resistant.
The picture and information sections are engraved with lasers so are harder to forge.
But, resident registration numbers are not included, so the new version can no longer be used as an identification card domestically.
Up until June next year, people will be able choose between the older green version or the new, navy blue one if renewing.
The price is the same at around 42 U.S. dollars and previously-issued passports can be used until they have expired.
