As in your example above -which really sounds interesting- one could have 1 unique key per WS to get access to that specific WS. In my case however, my plan is to use the iButtons to identify the different waiters (or bartenders) or clients in our club (actually a riding school) so they can put in orders on whatever WS or make payments (small cash transaction) on whatever WS. Now that I read your comments, I think I want to try another approach to this. On the same site they have info on TINI (Tiny InterNet Interface --www.ibutton.com/tini) wich does all the propietary iButton stuff and gets this info on the network. If I can get my server to read or track this info, I can access it with my WS's. Let's say I wanted to use the serial port for something else. A simple LCD display, showing the price the client has to pay. this can be different per WS. How to set this up (Hardware/Software) ?
