To be clear, where is the readout coming from ?
 
If each machine is running software, that reads the iButton, and stops at 30,000 logins. Then my questions would be
 
Is it the software that is stopping the logins at 30,000, in which case, can we bypass the software ? Or fix it.
 
Is it the iButton, that has a counter and won't go higher ?
 
It seems to be the software, in which case, booting from another system, and changing the system disk to bypass that software would probably work.

Thanks for the response Daniel, but sadly it is exactly 30k. The machine has a readout on the display which gives a warning at 25k and stops functioning at 30k. I'll post again when the 1-Wire usb and the scanner come in.

Thanks again for the responses!

I could be flat wrong but 30k is close to 32k, which is one of those
magical numbers.  It could be incrementing a counter that is evaluated
as a 16 bit signed integer (which overflows at 32767 + 1).   Depending
on the rest of the code, it could be as simple as changing it to a
long integer.
