I work at a gaming centre, and we plan to install RFID card readers that can be connected to a central server through ethernet. Customers would be issued RFID cards, and the credit in their account would be stored in the server. when a customer wishes to play, he/she simply uses his card, the reader identifies it, verifies from the server that the card holder has enough credits, and then begins the game, sending a message to the server about the same, whereby the server deducts the requisite credits from the particular account. I am looking for cheap (probably Chinese), but reliable RFID readers for this purpose. I tried googling, but it returns with either high-end (unaffordable) products, or those without ethernet. I want the reader to work online only, that is it need not be capable of working as a stand-alone device. something along the lines of door access controls, but without keypads or large in-built memories to store data.
RFID devices : help needed on manufacturers.?
