Help Finding RFID Reader & Interfacing for Senior Project

AI Thread Summary
The discussion centers on a college student's senior project aimed at replacing barcodes with RFID tags in retail settings. The student seeks assistance in finding a cost-effective RFID reader capable of reading multiple tags simultaneously and from several inches away, as well as interfacing with a computer for transaction displays. They also plan to integrate a magnetic card reader for simulating credit card payments. The student expresses difficulty in effectively searching for the necessary components online. The conversation highlights the challenges of sourcing technology for innovative projects in an academic setting.

Hello.

I am getting ready to start my senior year in college for EET. I had to come up with a senior project, design, and fabricate it. I have an idea of what I want to do but need help understanding it and what product is suffecient for my idea and cost effective for a college student.

Idea
I would like to desing a concept for replacing barcodes on items in any store with RFID tags. (I know that this idea has been thought of before but hasn't been made mainstream. I got the idea off of The History Channel) So the problem that I have ran into is finding a reasonably priced RFID reader that will read multiple RFID tags at the same time or with in a short period. Also the RFID reader must read tags several inches away.

I also need it to interface with a computer. I would like to use the computer to display the item, price, tax, and total. Then use the number keys to simulate paying with cash. I would also like to interface a magnetic card reader like a credit card reader to simulate paying with a credit card.

I am horrible at locating stuff on the internet. It seems I can never put the right parameters in google to get what I want.

Welcome back, ajustin.

You can read through the "Related Threads" at the bottom of this page (they are selected by title, I believe).

Also, wikipedia is often a good source of introductory material, and often has pointers out to more reading:

Thread 'Weird near-field phenomenon I get in my EM simulation'
I recently made a basic simulation of wire antennas and I am not sure if the near field in my simulation is modeled correctly. One of the things that worry me is the fact that sometimes I see in my simulation "movements" in the near field that seems to be faster than the speed of wave propagation I defined (the speed of light in the simulation). Specifically I see "nodes" of low amplitude in the E field that are quickly "emitted" from the antenna and then slow down as they approach the far...
Hello dear reader, a brief introduction: Some 4 years ago someone started developing health related issues, apparently due to exposure to RF & ELF related frequencies and/or fields (Magnetic). This is currently becoming known as EHS. (Electromagnetic hypersensitivity is a claimed sensitivity to electromagnetic fields, to which adverse symptoms are attributed.) She experiences a deep burning sensation throughout her entire body, leaving her in pain and exhausted after a pulse has occurred...
