International Mobile Equipment Identity. A 15 digit
unique code that is used to identify the GSM/DCS/PCS
phone to a GSM/DCS/PCS network.
When a phone is switched on, this unique IMEI number is
transmitted and checked against a database of blacklisted
or greylisted phones in the network's EIR (Equipment ID
Register).
If the EIR and IMEI numbers match, the networks can do a
number of things. For example, the can greylist or blacklist
a phone:
• Greylisting allows the phone to be used, but it can be
tracked to see who has it (via the SIM info).
• Blacklisting bars the phone from being used on any
network where there is an EIR match.
A binary bar code symbology representing character pairs
in groups of five bars and five interleaved spaces.
Interleaving provides for greater information density. The
location of wide elements (bar/spaces) within each
group determines which characters are encoded. This
continuous code type uses no intercharacter spaces. Only
numeric (0 to 9) and START/STOP characters may be
encoded.

Input/Output Control.
Mobile computers with an integrated imager use digital
camera technology to take a digital picture of a bar code,
store the resulting image in memory and execute state-of-
the-art software decoding algorithms to extract the data
from the image.
The space between two adjacent bar code characters in a
discrete code.
A bar code in which characters are paired together, using
bars to represent the first character and the intervening
spaces to represent the second.
