I work with a software development team inside local government. Our team have developed an app for Apple IPhone 6 SE with Cordova that requires carers to "check-in" to client visits. Clients typically are vulnerable people, like the aged and severely disabled.
We would like the check-in to be possible only when the carer is at a client's home. We absolutely need to ensure this, to prevent potential fraud.
One idea that has been touted is a fob kept in the client's home alongside their care docs. The fob will contain a code identifying the client. Only when the fob is plugged into the IPhone will the app allow checkin.
Would any of you know if such a device exists? Or a similar type of solution?
IBeacons have been mentioned but are too expensive per unit.
