There are many fears running through the minds of parents, but the biggest fear of any is whether or not their child is safe. With security cameras and home security systems, we put a lot of effort to ensure safe surroundings for our little ones. When our miniature selves begin roaming on their own two legs, the fear of them becoming lost is a never-ending battle. We can’t always keep our eyes on our children, but recent developments with barcodes and RFID tagging have derived some very realistic ways of keeping track of our most valuable possessions even when they’re out of sight.
A host devices’ camera is designed to take pictures, not to decode barcodes. Scanning barcodes requires a careful two-step process; focusing the device’s camera on a barcode to be clear on the screen, then scanning. The user then must toggle out of that device’s screen to view anything other than the scanned barcode. This affects the speed of the workflow. Every barcode must go through the same process – refocusing, then scanning.
Imagine a vendor speaking with an impatient customer who’s asking for a size 10 shoe that’s not found on the shelves. Rushing to the stockroom with blood pumping from exertion, carrying a cell phone in one hand and a scanner in the other. What’s the likelihood that salesperson WON’T drop one of those juggled devices?
