The BoxLock is a smart padlock that you can setup outside of your house to secure a package delivery container. It can be opened either via the mobile application (Android or iPhone) or by using the built-in barcode scanner to scan a package that is out for delivery. BoxLock uses a SOC (System-on-a-Chip) which contains the CPU, RAM, ROM, and flash memory all in one. My working theory is that this flash chip is used to store the barcodes of packages.
