A wearable device for a fully automated in-hospital staff and patient identification.

In the health care context, devices for automated staff / patient identification provide multiple benefits, including error reduction in drug administration, an easier and faster use of the Electronic Health Record, enhanced security and control features when accessing confidential data, etc. Current identification systems (e.g. smartcards, bar codes) are not completely seamless to users and require mechanical operations that sometimes are difficult to perform for impaired subjects. Emerging wireless RFID technologies are encouraging, but cannot still be introduced in health care environments due to their electromagnetic emissions and the need for large size antenna to operate at reasonable distances. The present work describes a prototype of wearable device for automated staff and patient identification which is small in size and complies with the in-hospital electromagnetic requirements. This prototype also implements an anti-counterfeit option. Its experimental application allowed the introduction of some security functions for confidential data management.
