 The latest computer craze has been to be able to wear wireless computers.
 The Computer Fashion Wave, "Digital Jewelry" looks to be the next sizzling fashion trend of the technological wave.
 .. The whole concept behind this is to be able to communicate to others by means of wireless appliances.
What is digital jewelry?
 Digital jewelry is the fashion jewelry with embedded intelligence.
 “Digital jewelry” can help you solve problems like forgotten passwords and security badges.
 They have the potential to be all-in-one replacements for your driver’s license, key chain, business cards, credit cards, health insurance card, corporate security badge, and loose cash
DIGITAL JEWELRY AND ITS COMPONENTS:
 Earrings - Speakers embedded into these earrings will be the phone's receiver.
 Necklace - Users will talk into the necklace's embedded microphone.
 Ring - Perhaps the most interesting piece of the phone, this "magic decoder ring” is equipped with light-emitting diodes (LEDs) that flash to indicate an incoming call. It can also be programmed to flash different colors to identify a particular caller or indicate the importance of a call.
 Bracelet - Equipped with a video graphics array (VGA) display, this wrist display could also be used as a caller identifier that flashes the name and phone number of the caller.
TECHNICAL SPECIFICATIONS OF DIGITAL JEWELRY:
 Digital jewelry devices consist of a screen or display for information, most likely consisting of 7-16-segment, or dot matrix LEDs, LCDs, or other technologies such as electroluminescent material (EL), speaker, a single flashing light
 A micro controller that is a surface mounted device (SMD) on a printed circuit board (PCB) with resistors ® and capacitors © are the internal 'guts' of the jewelry.
DISPLAY TECHNOLOGIES:
 The digital jewelry display, for instance, every alphabet and number system has found representation within the electronics realm and 'dot-matrix' is used to display Chinese and Japanese and other character sets, as can the alternative display for LCDs also be used, as often found in watches.
ELECTROMAGNETIC BEADS:
PROTOTYPES OF DIGITAL JEWELRY:
 THE JAVA RING:
 Dallas Semiconductor is developing a new Java-based, computerized ring that will automatically unlock doors and log on to computers.
Highlights of Java Ring
 Runs Java better (plus portions enhance Java Card 2.0)
 Careful attention to physical security
 Durability to stand up to everyday use
 High memory capacity (up to 134K bytes NV SRAM)
 Retail connectivity to 250 million existing computers
CONCLUSION:
 The basic idea behind the digital jewelry concept is to have the convenience of wireless, wearable computers while remaining fashionably sound.
 It is hoped to be marketable soon, however, several bugs remain. Charging capabilities and cost are just a sample of the problems that lurk
