What is barcode art?

Barcode art is created using the personalized data of a human being. When an individual's gender, weight, height, age and location are entered, a barcode is formed using real-world data. This barcode can then be printed, mapped, scanned, even depicted on a T-shirt or a coffee mug. Scanning this barcode projects the user's brand of humour. The calculation of an individual's BMI based on the height and weight data reveals the health of an individual. Thus, those considered underweight or overweight are worth less money. Thanks to the dominance of the US, all barcodes are published in inches and pounds.
