Why is this good idea to follow?
By setting Kiosks throughout the college, the bookstore not only can increase their sales, they can also
avoid human error. Cashiers sometimes make errors; shoppers have to wait for a long line when they
check out in the store. When setting the Kiosk, System process of sale of Kiosk would do the calculation
accurately and update automatically. shoppers can stop by anytime to check for items and request a
delivery service w hich would save time. Also, the bookstore can save money by hiring less cashiers and
avoid the possibility inventory error (shoppers read the description of item and agree by term before
purchased)
