ARTICLE SALE USING BARCODE SCANNER
Scan the article barcode. The article must have programmed barcode and price.
If the barcode matches with any article the sale is registered. Before scan is possible to set
quantity and price.
 ECR supports only barcodes compliant to EAN13, EAN8, UPC-A and UPC-E
standards. If working with unique barcodes, they must be programmed (see 2.2).
 Weight barcode can be used a variant of EAN13. This type of barcode contains
information about the number of the article in ECR and its quantity (up to 5 categories). It
is not necessary to program this type of barcodes as article parameters. Only the first two
digits need to be programmed, in the general parameters of ECR. (see 2.2).
The ECR interprets the barcode digits as follows:
YY NNNN X QQQQQ X
weight barcode prefix
Article number
Quantity checksum
(Not checked by ECR)
Quantity max. 99,999 Kg.
Barcode checksum
(Checked by ECR, depending on P27)
SALES WITH QUANTITY USING ELECTRONIC SCALE

The goods are put on the scales. When the weight of the goods is displayed in XX,XXX Kg
format, the key |is pressed. If the communication between the ECR and the electronic
scales is proper, the weighted quantity is displayed on the ECR. A long beep indicates no
communication. Pressing |key again starts a new attempt to get quantity information
from the electronic scales. There follows a sale of a department (article) following the
above described steps.
