*** DOWNLOAD PROJECT • PROJECT DESCRIPTION ***



The project consists of a local unit which is located close to the coffee machine. It is based mainly on an ATmega128 microprocessor, an XPORT to handle the ETHernet stuff as well as an RFID Add-on.
No exclusive (proprietary) IC was used to build the RFID Add-on, so every 125 kHz card will work !
It is advantageous to have an usb RFID stick to handle payments / registration.

The second part is the website which handles the counting, displaying as well as the payments.
Every user - who is registred when receiving the badge - can see his nickname and the balance.
The information is stored in a flat textfile, so no SQL database is needed.
Some security features are not part of the documentation :-)

Detailed Description of the Components :



1) RFID-Board ::



The simplest solution showed to be the best. There is no need to get a "Special IC". You just have to put a
carrier (125 kHz) into the air and have the badge do the work. The action of the badge is then monitored
with a simple diode detector, recovering the information from the envelope of the carrier.

2) ATmega128-Board with the XPORT ::



This board is just a standard application of the ATmega128. Nothing special, so far. XPORT is connected
to UART1. RFID Board attached on the right side.

Achtung

1) No, we do not sell anything. PLEASE DON'T ASK.

2) Commercial use of the Target.3001™ files is strictly prohibited !
