Which type of data matrix code is often utilized in serialization for holding significantly more data than older linear barcodes?
Answer
2D data matrix codes
Serialization, the practice of tracking every individual salable unit, necessitates data-holding capacity that simple linear barcodes cannot provide. Modern track-and-trace implementations often rely on 2D data matrix codes, such as QR codes. These two-dimensional codes are capable of encoding substantially more digital information per square inch compared to traditional one-dimensional linear barcodes. This increased data density is essential for embedding the unique identifier required for unit-level verification and authenticity checking at the point of dispensing.
