Barcodes containing newborn babies’ fingerprints are being used to prevent mix-ups over identification.
The system has been introduced in the maternity unit of La Zarzuela Hospital in Madrid, Spain.

As soon as babies are born their fingerprints, and those of their mothers, are stored in electronic barcodes which mother and baby wear on their wrists.

The barcodes also contain other information, including the mother’s details and information about the doctors present at the birth. In effect, they act as an ID card for the child.

If there is any doubt about a baby’s identity, the barcodes can be scanned by a machine which matches the child with its mother. More here.
