Blockchain prepaid POC

A prepaid payment is money loaded in advance, like a transit card balance, and a blockchain ledger records who owes what without passing every step through multiple middlemen. iM Financial Group said on April 20 it finished a proof of concept that used that model for QR-code payments. (digitaltoday.co.kr) The pilot was run by iM Financial, its banking unit iM Bank, and Buchigo, a startup inside iM Bank’s fintech incubator Pium Lab. Consumers paid by scanning a QR code, while prepaid balances were linked to verified-name iM Bank accounts. (digitaltoday.co.kr) Instead of routing settlement through the usual stack of card-network and processor intermediaries, the test used a distributed ledger for clearing prepaid QR transactions. iM Financial said that structure could lower payment fees and reduce merchants’ cash-flow burden. (en.bloomingbit.io) The project was built inside South Korea’s legal framework for prepaid electronic payment instruments under the Electronic Financial Transactions Act. iM Financial said the trial met real-name verification, anti-money-laundering and user-protection rules and showed “commercial-grade stability and processing speed.” (digitaltoday.co.kr) QR payments already matter at scale because they are cheaper for merchants to accept than traditional point-of-sale hardware and have become a major part of wallet use. IBS Intelligence has separately reported that QR-code payments were expected to account for 40% of global digital-wallet transactions in 2025. (ibsintelligence.com) South Korea is also rewriting rules around tokenized finance, which helps explain why a bank group is testing blockchain rails now instead of waiting for a full product launch. The Financial Services Commission said in March that amended security-token legislation approved by the National Assembly in January 2026 is scheduled to take effect on February 4, 2027. (fsc.go.kr) That timetable matters because iM Financial framed the prepaid test as an early move ahead of broader institutionalization of tokenized securities and stablecoins. The group called the pilot part of a “hybrid strategy” that keeps blockchain payments inside current financial rules. (digitaltoday.co.kr) Other payments groups are pushing QR infrastructure in parallel, though not with the same prepaid-on-chain design. IBS Intelligence reported last week that cross-border QR payments in ASEAN reached 36.2 million transactions worth $716.4 million in 2025. (ibsintelligence.com) For now, iM Financial has reported a proof of concept, not a nationwide rollout. But the test puts a concrete date on a question banks have been circling for months: whether cheaper QR payments can be settled on-chain without stepping outside existing regulation.
