Touch Memory iButtonsTM
The iButton is a
computer chip housed in a durable 16mm stainless
steel cam. They use no power, require no
maintenance, and will resist dirt, dust, chemicals,
water, weather, and rough treatment. Each chip
contains unique identification information. Every
time a person uses the button, the Read Head records
the identification number.
You can use this
information to keep track of assets, limit access to
equipment, and log the use of equipment by that
person. You can also use this information to charge
for equipment use. For more information about the iButtons, contact Dallas Semiconductor through their
web page at
http://www.maxim-ic.com/products/ibutton.
Using the iButton is
simple. The user just presses the button against the
Avdata Touch Memory Read Head for a moment.
Information is electronically transferred from the
button to the Read Head. There is no electrical
contact.
