Introduction
Bar codes
A bar code is a graphic encoding of a number signifying a product according to strictly defined internatio-
nal regulations. If a product has a bar code assigned, the bar code is depicted on each packaging for this
product. The most frequently used codes for products in Europe are the 13-digit code according to the EAN
norm (EAN - 13) and the 8-digit code (EAN-8). The Euro-50T Mini cash register is also capable of working
with EAN bar codes which contain an expanded 2 or 5-digit section.

Cumulative totals (grand totals)
Cumulative totals are variables that calculate the values of all sales. Three types of grand totals are generally
known: GT1, GT2 and GT3, which are defined by Regulation no. 55/1994 Code of Laws on the method of
recording sales through electronic cash registers, as amended, as follows:
GT1 - gross turnover - this means the cumulative total of all positive values registered in the electronic
cash register (ECR).
GT2 - net turnover - is understood to be to the difference between gross turnover and negative turnover.
GT3 - negative turnover - meaning the cumulative total of all negative values (refunded items), discounts
and negative items registered in the ECR.
