Mark Hoskins seems to be on track:

To see how we might allocate and account for goods and services on a communist basis, we just have to look at existing technology and join the dots. An application like Waze with a barcode scanner that used GPS location could take a realtime snapshot of what was being taken from stores and consumed in a given location at a given time. You could take your weekly shop from the store, scan the barcode as you unpacked it then scan again when the item is consumed – people already do similar things with health apps to track their diets. This, combined with ‘wish lists’ would give an accurate picture of peoples’ needs and desire and would be not skewed by price mechanisms. People would take the things from the store they actually want, not what they can afford. Production would be regulated, not by the market, not by central planning, but by the sum total of decisions made by individuals in the pursuit of their own needs, wants and happiness – the invisible hand of communism.
