Touch screen panel and RFIDs online

I am a person who loves tinkling with things and I love reading all about the latest in technology and stuff also. Just recently, I decided to experiment on my old laptop which was ancient by the way as it does not even have docks for USB or wifi..simply a modem PCMCIA. I decided to make it a part of my network as a firewall by installing PCMCIA reader which I bought online in elatecworld.com. It was also in this site where I bought our company’s touch panel monitor for our building’s lobby to serve as an information desk of sorts. Also in this site is one of my favorite tools, the RFIDs which are being used in most department stores or even in scientific research or even security purposes. It utilized a 2.4 GHz which is the latest in this model and so powerful in a sense. RFIDs can even be used for tracking as it can reach for miles at a time which makes it so interesting for me as I have an interest in spy-type gadgets like this.as it brings out youthful memories when I watched all those fantasy and fiction movies about these stuff.
