What business wants an extra 100,000 pesky customers tromping through its stores on a daily basis?
The RFID Journal reports in “RFID and Global Warming“:
… Wal-mart has estimated that inventory management through item-level RFID tagging within its stores has the potential to eliminate extra trips for 100,000 customers daily — customers who would otherwise seek products elsewhere. The retailer has calculated that this would result in the elimination of 80,209 metric tons of CO2 per year…
FYI, 80,209 metric tons of CO2 amounts to about 0.00027% of annual manmade emissions of greenhouse gases.
