PDA Solutions dont Measure
Even during normal use problems with both products kept popping up. Neither BioHub nor BioSentry reliably recognized registered users - a state of affairs that repeated soft- and hardware resets were unable to remedy. Sometimes it took 30 attempts for a simple authentication to succeed, then again placing the very tip of a fingertip of an unregistered user on the sensors surface would suffice for access to the PDA to be granted. In a nutshell: Since there was no way to sensibly test either BioHub or BioSentry, we put them back where they had come from - inside their FedEx packages.
