@NAZAARMUSIC@emmibish I have to comment on this from a business perspective, as someone who sells identical products to what he is selling. Margins are not slim, there is an incredible amount of markup on these products even with having a high quality product.
@Waltonchain Postal/Mail companies like Fedex, DHL, etc. Luggage tracking in airports to streamline bag processing. Warehouse tracking like Amazon FBA warehouses where saved time means more money.
