RFID reader project...

I have been asked to check a possible setup to a RFID reader system...
The basic idea is 1-3 antennas connected to a reader module, that talks to a card-sized computer (Arduino like), that card-sized computer will talk to a server via WiFi (REST over HTTPS)...
Or on the other way around the reader module will be paired with a WiFi module and will directly talk to the server (no card-sized computer in the middle)...
The system should read passive RFID cards (stickers mostly) in a range of 1-2 meters with a frequency of 10 cards a second...

I have read a lot of about it (and have some ideas), but there is nothing like experience...

If you have, I would love to hear about it...

UPDATE

I have ordered this http://www.atlasrfidstore.com/thingmagic-m6-uhf-rfid-reader-4-port-development-kit-with-ac-power-and-wi-fi/[^] to start and play with the ideas I have...Do you know it? Do you know something better in the same line?

UPDATE 2
For those bookmarked this question...I added a second question around this project...
RFID reader project... Take 2[^]

I would like to hear any info from your work experience...
