Before making a purchase, finding someone who can help with the right level of knowledge is often difficult. Installing a Kiosk that links a network of available resource able to answer questions immediately over a video link gives a far superior level of customer service.
Links can be built into a company website so customer questions can be answered by a remote expert.
Various booths are available for more personal discussions. For example, for use in pharmacies for medical advice or banks for personal financial advice.
One such product available is the one provided by vpod, which is a very neat, personal booth.
