Label

Labels display information on products and packages within limited space. QR code labels transcend physical space constraints - a small cosmetics label can't print full ingredient lists, but one QR code links to ingredients, usage videos, allergen info, and manufacturing transparency.

Logistics labels use QR codes for real-time delivery tracking. GS1 QR codes consolidate GTIN, lot number, expiration, and shipping data on one label. Size constraints are the main challenge - minimize stored data, use error correction Level L, or consider rMQR for elongated labels.
