Hi Brad
Sure.
First you will need the ability to read and write to standard iButton hardware.
There are several options.
This is what I use
https://www.ibuttonlink.com/products/ds1402d-dr8
and
https://www.ibuttonlink.com/products/ds9490r
There will be other sources so it worthwhile searching for a supplier near you.
Once you have that hardware, you will need software.
Again there are several options.
The doco that comes with the hardware should give you guidance.
Your solution will depend on whether you use a PC or an Apple, or something else.
I use a PC.
Feel free to ask, I may be able to offer limited support.
