A microchip implant may be life-saving for people with chronic medical conditions while giving people with physical disabilities a sense of independence.

Microchips that allow people to open coded doors and make payments without reaching for a credit card, could help people with disabilities, like quadruplet amputee Alex Lewis.

A few years ago, what Lewis thought was a common cold turned into Strep A toxic shock syndrome, septicaemia and necrotising fasciitis – a flesh-eating disease. He’s lucky to be alive, but it came at the cost of his arms and legs.

Today he has a microchip in the remains of each arm. The one contains key codes for his home and the other contains his medical information. It gives him some independence back while providing his medical records in case of an emergency. He’s hoping that he will soon be able to use a microchip to drive a car.

Microchips could help more disabled people like Lewis, but it could also be an aid to anyone who may not be able to answer for themselves in case of an emergency, particularly diabetics and epileptics.
