We don’t often report on fridges, but we noted that ShelfX said that it has processed more than four million transactions in its system which allows customers to open the fridge using a credit card and help themselves. The system also now supports the Venmo app which allows prepayment. If there is $10 in the Venmo account, the fridge will open. The system allows consumers to pick up and put back items if they want and provides a wide range of analytics to help owners to understand the patterns and how consumers are reacting to products.
