1-1-3 Binary Level and Multiple Level
1 Binary Level and Multiple Level
Bar codes in the categories of CODE 39, CODABAR and ITF consist of bars and spaces that have two
steps of narrow and wide widths. It is named the "binary level" bar code.
The ratio between narrow and wide is 1 : 2 to 1 : 3. Some allowance is possible.
Narrow bar
Wide bar
Narrow space
Wide space
Bar codes in the categories of EAN and CODE 128 consist of bars and spaces that have four steps of
narrow and wide widths. It is named the "multiple level" bar code.
The ratio is 1 : 2 : 3 : 4. Allowance is very limited.
One Point
"Multiple level" EAN and CODE 128 have four steps of bar width. If the print quality is not
good enough to identify the bar width, reading error tends to occur.
The printers with poor print quality including dot impact printer are not suitable for EAN
and CODE 128.

1) Sales management
Use of a bar code allows everybody to work on a cash register without any difficulty. The system
supports the workers who are not skilful with cash register operation, so that the customers may not be
forced to wait for a long time.
Counting the daily sales amount can be done instantly.
* EAN code does not have price information. The price information can be obtained from the
computer by reading the bar code of the product.

2) Stock and purchase management
As the system provides information on real time base on;
Who bought the product?,
What time the product was bought? and
Which product was bought?,
it is now possible to purchase the required product at the required time.
Since it is difficult for stores with limited spaces such as convenience stores to keep enough stock, it is
very important for them to purchase the salable products in salable quantities. For the foods with
consumption validity like box lunch, it is not allowed to display them for a long period of time. The
system allows the arrangement to purchase at the required time in the required quantities.
3) Understanding consumer trend
Any information can be collected on real time base on;
What is the most salable product?
What customers are to be targeted?
What is the least salable product on the other hand?
What campaign brought the successful sale?
The information is very useful for deciding management strategies.
