If it has the MyCare card in it:

“When dealing with a medical emergency, patients may be unconscious or unable to communicate with paramedics for some other reason,” says Professor Panicos Kyriacou of City University, “our device makes potentially life-saving data easily accessible. For example, it’s vital to know whether a patient is allergic to latex. If they are, use of latex gloves by a paramedic might be fatal.”

The MyCare Card is designed for voluntary use by patients. All data would be held on the card securely so that it could not be accessed if the card were lost.

A patient would keep the card in their possession and add or alter a range of personal information (e.g. on next of kin) on their home PCs. A plug embedded in the card is simply slid out and inserted into a computer; bespoke software then automatically runs from the card. This personal medical data-browsing software was also developed as part of the project.
