BioSmart

BioSmart makes smart cards, the chip-embedded plastic cards used for credit and payment transactions, and operates several other distinct businesses including pharmaceuticals, alcohol-payment systems, book publishing, diagnostic kits, and heavy-electrical-equipment manufacturing and repair.

Its products and services reach consumers and businesses across these varied industries. Listed on KOSDAQ, Korea's tech and small-cap exchange, the company deliberately spans unrelated sectors as a strategy to manage the risks that come with operating in a mature, slow-growth core market.
