The Life-Saving Receipt

Because of language barriers and a lack of medical information, the vaccination rate for migrant-background children stood at just 55.2%. 'The Life-Saving Receipt' printed essential vaccination information directly on receipts whenever migrant families bought childcare items like diapers or formula at local stores they already visited. By delivering information at exactly the moment it was needed — without anyone having to search for an ad — the vaccination rate for the targeted children rose to 80%, turning an ordinary receipt into a life-saving piece of media.

In South Korea, only 55.2% of migrant-background children are vaccinated despite free eligibility. The Life-Saving Receipt turned everyday local stores into a healthcare channel: buying baby products triggered a multilingual receipt with QR links to vaccination, interpretation and counseling support. It helped 80% of previously unreached children get checkups, drew over 1,000 institutions, and prompted a National Assembly forum.

Migrant families in Korea often cluster by nationality within tight neighborhoods and face language barriers to healthcare. Neighborhood stores selling halal or Vietnamese goods act as trusted community hubs, which made them an ideal delivery point.
