Cardport: Busan’s Card Market at a Glance

Field notes

Cardport separates sale, purchase, and exchange activity into structured listings, with visible examples labeled by product, district, and elapsed time. Its price search accepts a card name, number, or set, while related tools cover shop and pop-up locations, store stock updates, and image-based centering measurements. The site also distinguishes KakaoTalk’s real-time conversation from its own organized market records and disclaims custody or brokerage of goods and payments.
