This is my active badge. I wore a badge like this for quite a number of years in the late 80's and early 90's. This is the last one I was issued with. They were designed originally by Roy Want of Olivetti Research.
The badge operates only in specially-wired buildings, where each room and door has an infra-red transceiver to communicate with the badge.
The badge was used to unlock the buildings where I worked and to give out my location. In early days, the unix finger protocol was augmented to give out badge locations, but later the WWW was used. Badge sightings were also used to index multi-media recordings.
To a large extent, people stopped wearing their badges in the office environment once they had a mobile phone.
It's amazing what you can do when you embed a MCF51JM128 ColdFire USB MCU, a MMA7260QT 3-axis accelerometer, a MC34673 Li-ion battery charger IC, a MPR084 capacitive touch sensor along with an LED screen into an event ID badge. Add a little ingenuity and programming, and you can have a multifunctional badge - even a toy.
The Flexis JM Badge Board doubles as an event badge for the Freescale Technology Forums around the world and provides design engineers with a low cost development board to develop a unique application.
Many folks received these
and modified them with programming and hardware changes.
The RFID badge was silk-screened to double as a human readable event badge!
The unpopulated PC board were used for the remainder of the attendees.
The main chip is a TI MSP430: X430F2618T rev F

including MSP430; Zigbee, RFID and wireless tutorials

Folks were advised to remove the battery if they didn't want to be tracked in real time.
The missing FTDI FT232RL chip and USB connector were sold separately
for programming the TI MSP430 via USB for those without JTAG adapters.
It's the same form factor as
I put it in the tin for RF shielding!
I wore my

badge holder with the HOPE badge
and the Freescale badge scrolling the message "NOT RFID!".
A few folks already have the Freescale badge and others were intrigued
by how much was included in the base product compared to a bare Arduino.

Badges are $49.00 in three varieties: Guest (blue) Staff (white) Speaker (black)
DEFCON 20 (July 2012) had the earlier version
with colored & shaped PCB artwork, no OLED display.

The Micro Bit is an ARM-based embedded system designed by the BBC for use in computer education in the UK. The device has been given away free to every year 7 pupil in the UK, and is also available for purchase by anyone.
Measuring 4 x 5 cm the device has an ARM Cortex-M0 processor, accelerometer and magnetometer sensors, Bluetooth and USB connectivity, a display consisting of 25 LEDs, two programmable buttons, and can be powered by either USB or an external battery pack. The device inputs and outputs are through five ring connectors that are part of the 23-pin edge connector.
The Calliope Mini is essentially a micro:bit clone, but one that has learned from the experience of its spiritual forefather. The connection points are spread around the outside of the board where the crocodile clips won't accidentally touch each other.
Not content to simply copy, the Calliope also adds additional functionality. A microphone and speaker are integrated onboard, as is a Grove-style I2C connector. They've even added a TI DRV8837 H-bridge motor driver, so students could make a rolling robot straight out of the box.
