I went to the post office mail the ebay items I sold, insurance claim of my lost luggage together and a complain letter to Air Canada after work today. I am surprise the postal fee is quite expensive, especially when confirmation is required. In the modern fully computerized postal service, I wonder what is the incremental cost of assigning tracking number to each letter and parcel. Send a regular letter within Canada is $0.5, send a registered letter is $6.5. I have to pay $6 extra just for the confirmation of delivery, what a rip off. In near future, stamps will be embedded with RFID tags and all postal infrasturture from mailboxs to central office will have internet connected RFID reader implemented. This will provide a real time online tracking system to let the end users pin point the where about of their parcel.
