US Patent 10417603 Secure package delivery

Wireless presence is used as a theft prevention mechanism for packages. When a package is shipped, the package includes a wireless security device. When the package is delivered to its final destination shipping address, the wireless security device is activated and programmed with a security credential. The security credential, though, is based on information obtained during an initial purchase. The wireless security device may thus only be deactivated by a recipient participating in the initial purchase.
