Verizon – Counting a rack of phones in one scan

Verizon holds large inventories of phones and devices across stores and warehouses. Stock managers kept stock levels right by scanning every box on every rack, one at a time.

Working at GGK, I designed an Android app that scans a group of boxes at once. The system detects the code type on its own, whether IMEI, UPC or QR, so nobody has to pick a mode before scanning. When a box has no usable barcode, staff can scan by image instead: photograph one box as a reference and the app finds every box that looks like it.

The flow is deliberately simple for people on their feet all day. Choose the store and rack on a map, scan, check the results in History, then update stock in one confirmed step. The red Store / Rack bar at the top makes sure every scan lands in the right place. I also designed the unhappy paths: camera access denied, low light, duplicates, unreadable codes and failed updates.

We estimated the video scanning approach could save over 500 hours of box-by-box scanning.
