At its core, it is a digital stamp and an app. If you want to send a parcel, you’d simply stamp it with a device that uses a laser to etch it with your name and a unique identifying pattern. After that, the USPS would pick up your package; from there, the app would prompt you to provide the name of the person you’re trying to reach.
The problem is, will such a fine print even survive a journey?, how far can you send it before all the handling and sorting will make the mark unreadable to the sorting machines in the delivery office, or even worse maybe they will mark it as a fraudulent stamp(as someone has to pay for the shipping in some way) and they will "throw" it away"

I would not mind a cash-free economy as there are free services here that you can transfer money to people just based on their mobile phone number
thou I see that the most poor would suffer the most and not the criminals that can trade in different ways, the beggers/homeless that does not have bank accounts and the street artitsts, I dont mind thoose and it would be a shame that they would have it harder
you see that unlike you that whom I assume is a console-peasant we the PC MASTER RACE does not want to use more equipment than our glorious PC, the point of the PC is to have all in the same place and dont bother with things like a tv or something else that is not a PC.
Now comes the mobile phone, as people tend to upload pictures of their glorious bodies or bother us with things like kik or sms we now have to have one hand on the mouse and the other on the phone, meaning we will now be fully occupied with our hands.
A keyboard and mouse configuration helps us watch pictures of kittens and write comments about how other people are wrong and between the writing we can pick cheetos up from our bellybutton-bowl but now to hold a phone in the hand that does the cheetos picking, and that is just not right.
And for your second question, simply to run apps.
