A QR‐coded microtaggant for the anti‐counterfeiting of drugs is proposed that can provide high capacity and error‐correction capability. It is fabricated lithographically in a microfluidic channel with special consideration of the island patterns in the QR Code. The microtaggant is incorporated in the drug capsule (“on‐dose authentication”) and can be read by a simple smartphone QR Code reader application when removed from the capsule and washed free of drug.
