Gloves, dressings, syringes and test kits run out at the worst moment. In many practices and clinics the supply room is checked by eye, the reorder list is a note on the door, and the person who orders has to guess which size or variant was meant.
A regular count fixes that, but counting with paper means writing product names by hand and typing the list again for the order. Small differences between similar products get lost on the way.
Every package already carries a barcode that identifies the exact product. Scanning it and typing the quantity on the shelf turns the count into a clean list that purchasing can work from directly.
