In and On-Counter Stationary Scanners

Magellan®, Datalogic’s family of xed position retail scanners belong to this category and include presentation/sweep scanners,

single plane scanners, and Bi-optic scanners These types of laser scanners are non-contact scanning devices which are used

for medium-to-high volume retail scanning environments such as supermarkets, hypermarkets, drug, convenience and specialty

stores They easily connect to your point-of-sale terminals for data collection and reporting

Bar Code Systems

Bar code systems require three elements:

Origin: You must have a source of bar codes These can be preprinted or printed on demand

Reader: You must have a reader to read the bar codes into the computer The reader includes an input device to scan the

bar code, a decoder to convert the symbology to ASCII text, and a cable to connect the device to your computer Datalogic

markets a variety of hand-held products, which are decoders and input device all in one

Computer System: You must have a system to process the bar code input These can be single-user, multi-user, or

network systems

Origins of Bar Codes

A bar code system must have a source of bar codes and a way to read them Bar code labels fall into one of the following

categories: preprinted or printed-on-demand

Preprinted Bar Codes

Using preprinted labels is the most economical way to get high-quality bar codes This places some restrictions on you, because

the information in the bar codes must be determined in advance In many cases this is acceptable, but in some it is not

Preprinted bar codes are used where very durable, high-quality labels are necessary to withstand the environment (such as on

printed circuit boards), or where high-volume packaging or labeling is done Examples of preprinted bar codes are:

Bar Codes on Packaging The most common example of preprinted bar codes are those you see on packaging for retail

sale Grocery stores are the most common application, but the system is gradually working its way up the manufacturing

chain

Stickers or Tags In many cases, you need to identify a particular item as unique There are several companies that will print

stickers, pallet tags, item tags, or other types of very high quality bar code labels in any required sequence Either of these

systems works very well when you can manage the assignment of codes beforehand In many cases, you can also use

assigned codes by generating a correlation between the bar code and another signicant value For example, you could use

a randomly numbered sticker or tag and have the user type in the corresponding invoice number, control number, or other

information that goes with it

Printed-On-Demand Bar Codes

On-demand bar codes are used where the bar code must contain some information that is available only when the bar code is

generated Datalogic produces products to help with creating on-demand bar codes

On-demand bar codes can be produced in small quantities for less money than preprinted bar codes, and in less time They can

be printed with:
