Customers don’t want to wait, they want everything now and, consequently, POS software that enables on-demand purchases is increasingly popular. For example, store specific payment apps enable customers to purchase food or goods in advance, so when they arrive in store, their purchase is ready and waiting for them – no more queuing for the morning coffee. Having tablets and other devices in store for customers to use also enables them to pay there and then when browsing or look up information for themselves, in store.
