What are the Advantages of iButtons Over Other Technologies?

When developeing a solution to meet your application needs there are many technologies on the market to consider along with iButtons. Bar-codes, RFID Tags, Magnetic Stripe, Prox, and Smart Cards to name a few. Unlike Bar-codes and Magnetic Stripe cards, most of the iButtons can be read AND written to. In addition, the communication rate and product breadth of iButtons goes well beyond the simple memory products typically available with RFID. As for durability, the thin plastic of Smart Cards is no match for the strength of the stainless-steel clad iButton. Also, when comparing these technologies on the basis of security, there is no match for the iButton.

iButton Applications

Conversant in the universal digital language of 1s and 0s, the iButton, has circled the world as a peripatetic extension of the computer. iButton technology has found a home on every continent, with the possible exception of Antarctica - and we're not certain about that. The button's unique form factor and features address widespread cultural and economic needs: to identify and authenticate, time- and date-stamp events, guard property, and track inventory.
