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.maximintegrated.com/en/products/comms/ibutton.html.

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.
