And is it feasible to insert tracking information in these tags via a computer application?

I am unsure what you are trying to achieve and I don’t know what “3Ks” are, but I will try to answer your question as best I can. Many cell phones contain a built-in Near Field Communication (NFC) reader. NFC is a short-range form of radio frequency identification (only a few inches) that has some special characteristics. You can read NFC tags with your cell phone and transmit the information collected via that phone.

It is possible to write information to the tags with a cell phone or an NFC reader that connects to your personal computer or laptop, but I don’t know what you mean by “tracking information.” The transponder has a unique serial number that can be associated with a specific location or object. So you could put an NFC transponder on a campus map, for instance, and have people scan that transponder to trigger the launch of a Web page, a mapping application on a phone, or a custom-designed app.
