My incoming package notifies me about arrival time

My package inside the FedEx truck, alerts me when it is coming towards my house (delivery address) so I do not have to wait for two hours to collect packet, but can leave for my house only half hour before. The pacakge can have an RFID tag, which is read by RFID reader on the truck, and then sent to my cell phone, via SMS or alert me through email.
This would allow me to take less time off from work, and first time delivery rate of packages would increase as well.
