At present , I am using a linear barcode reader
( to input passwords in one of my computers ) given to me by a pharmacist ,
( because , in Turkey , now , all of the pharmacies are using square
barcodes
in drugs , etc.  to track the products produced ( declared to the
government ) and
given to the patients in pharmacies ( again declared to the government to
get payments ) ) .
In our country , all of the people are getting their drugs ( ... )
supplied by the government free of payments ( sometimes with very little
payments )
through the pharmacies  and hospitals .

We could not find a square barcode reader sold
by drug suppliers in our town because all of the pharmacies  already had
bought their units .


When a keyboard emulator barcode reader is used , there is no need to
use any other programs or devices . The processor of the barcode readers
are decoding the picture and sending its characters to the computer as if
they are
given from the keyboard .

The other kind of barcode readers ( i.e. , scanners of the barcode picture )
attached to a computer require their associated software  if
they are not keyboard emulators and
their ports are not able to generate keyboard input from data sent by
the barcode reader . Such barcode scanners are used if the scanned barcodes
are not
included into the ( let's say ) commodity scanners used in the shops .
