RFID access system. I am looking for a programmer of the custom access system (web application, interface, RFID reader 125 kHz with TCP/IP).
Hardware: RFID reader will be placed on the door to the Room. The output of this RFID reader will release the electronic door lock and let the user inside of the Room. User will use his own and unique 125 kHz RFID tag.
Interface between hardware and server: After user puts his RFID tag in front of the RFID reader, reader will prompt the server with query, if the user is allowed inside the Room at the current time and date. This will be done via TCP/IP interface, preferably RJ45. If the server sends the positive response, the reader will release the door lock and lets the user inside the Room. If the server sends the negative response, the RFID reader will beep three times and the LED will flash red.
Web application: The webpage will have its own domain for now, but can be implemented to a more robust system in future. User will open a URL and using his username and password he logs in. There will be a calendar where the user can book a time in the Room. He will be able to see other users' bookings, in other words utilization of the Room. The webpage will be multi-platform.
a) there will be a set of master RFID tags, which can open the door under any circumstances
b) admin of the webpage has readwrite access to events and users of the system:
b1) delete/edit/create event
b2) delete/edit/create user
b3) delete/edit/create RFID tags
b4) set the maximum time of one booking
b5) permanently or temporarily restrict single user (or set of users) from accessing the Room
b6) limit the amount of booked time for each user on daily/weekly/monthly/yearly basis
b7) can access stats of usage on daily/weekly/monthly/yearly basis and based on single or set of users
Site: Kosice, Slovakia, Europe

Amount: Access system for 1 door.
Material of the hardware: plastic or metal, dark color, nothing too big! Preferably dimensions similar to a small envelope (A6).
