“…Unique objects, barcodes, quick response (QR) codes, radiofrequency identification, and holograms are commonly used for product integrity and brand protection with a focus on supply chains. [13][14][15][16] In the United States, the Drug Supply Chain Security Act has mandated the establishment of unit-level traceability by 2023. Therefore, many US pharmaceutical manufacturers, retailers, and distributors have agreed to create blockchain technology for better managing complex pharmaceutical supply chains (also known as the MediLedger Network).…”

Online pharmacies and social media platforms are responsible for the growing presence of counterfeit medicines, and the verification and authentication of dosage levels are imperative for protecting individual medicines. However, the existing anticounterfeit methods for medicines and exterior box‐level protection are often limited, and they focus on pharmaceutical supply chains instead of empowering patients. Here, bioprinting and taggant construction of camouflaged biosafe quick response (QR) codes are introduced for on‐dose (or in‐dose) medicine security, integrated with the dosage form. Machine‐readable color QR codes contain concealed invisible patterns with biologically safe near‐infrared absorption properties, which help enhance the security of conventional QR codes. The reported bioinkjet printing and protein taggant construction guarantee printability, imperceptibility, stability, biocompatibility, digestibility, and tamper resistance to be an inherent part of each unit of medicine in solid dosage formats. Camouflaged biosafe QR code taggants can offer various medicine security applications including anticounterfeit measures, authentication features, track‐and‐trace, and serialization at the dosage level. This approach is expected to empower patients to play an active role in fighting illicit medicines and pharmaceutical products.

“…In recent years, some new barcodes based on colorimetric, [ 1–3 ] spectral, [ 4 ] photonic crystal, [ 5,6 ] hydrogel, [ 7,8 ] intelligent structural color material, [ 9,10 ] luminescent, [ 11,12 ] and magnetic [ 13 ] effects have been studied for their ability to record/transfer different domain information that cannot be supplied by the conventional one. However, these technologies either require complex synthesis techniques or are not compatible with the existing encoding/decoding system.…”

An intelligent encoding/decoding scheme for barcodes is studied that can realize transformation among different barcodes under external stimuli. The proposed scheme is compatible with the European Article Number (EAN)‐13 encoding/decoding system. First, the transformation mechanism among different barcodes is analyzed. Two different transformation strategies, the bar transformation and the background color transformation, are discussed. To demonstrate the possible applications, a temperature‐sensitive barcode tag (TSBT) and pH‐indicative barcode tag (PSBT) are developed by embedding the corresponding thermochromic and pH‐sensitive materials into the traditional EAN‐13 barcodes. Except for the conventional identification function, these tags can be used as environmental sensors to sense temperature and pH values. The maximum recognition rates of the TSBT and PSBT are 100% and 98%, respectively. The technology is universal and versatile because different kinds of sensitive tags can be constructed easily. This sensitive barcode technology can be expected to provide an efficient, accurate, and low‐cost solution to real‐time detection.
