Sufferers of Alzheimer’s disease are often in danger of wandering away from their caretakers. In nursing homes, RFID can be used to keep track of senile patients and allow hospital staff to be notified if they leave the building.
RFID key cards are commonplace now. The systems have been embraced for their security benefits. For one, lost cards can removed from the computer’s list of viable keys. This is like changing the lock only for lost keys. Computerized key-card systems also prevent anonymous entry. Since each key is individually numbered it is possible to detect who has entered or left thus preventing fraud or theft. Until recently this has been almost flawless from a security point of view.
