Access

Getting in and out – access versus accessibility

 

Access to a great number of places is, today, largely controlled by machines. Gone are the days when the smiling man was there at the entry point to provide access or lift the barrier and wave you through. Today it's more likely you will be greeted by electronic barriers that demand authorization in the form of smartcards and codes, finger prints or facial recognition before you can enter a site. While many of us take this form of controlled access for granted, others don't find it so easy to use the systems.
