Nursing and care homes constantly struggle with providing evidence of regular checks on the elderly to check they are alive. My idea is to create a barcode that fades if the body becomes cold.

This would allow a carer to scan the individual and provide a record of these checks. If the person has died the barcode will not be visible and thus the carer will not be able to successfully scan the individual.
