Metal Cards
The Metal Card and the iButton® together make a wearable computer that is hard to beat for compactness and indestructibility. Both are metal and stand up to the punishment of everyday wear. But while the Metal Card is eminently wearable and economical, it’s the Java™-powered iButton® that delivers the computing power. No matter how you wear it, here’s what you get with your Java™-powered iButton®: iButton® not included.
Note to customer: The iButton® needs to be ordered from Dallas Semiconductor prior to installation the iButton® to the Metal Card.
