Symbol Check Character

A symbol character or set of bar/space patterns included within a GS1-128 or GS1 DataBar Symbol, the value of which is used by the bar code reader for the purpose of performing a mathematical check to ensure the accuracy of the scanned data. It is not shown in Human Readable Interpretation. It is not input to the bar code printer and is not transmitted by the bar code reader.

Symbol Contrast

An ISO/IEC 15416 parameter that measures the difference between the largest and smallest reflectance values in a Scan Reflectance Profile (SRP).

Symbology

A defined method of representing numeric or alphabetic characters in a bar code; a type of bar code.

symbology element

A character or characters in a bar code used to define the integrity and processing of the symbol itself (e.g., start and stop patterns). These elements are symbology overhead and are not part of the data conveyed by the bar code.

symbology identifier

A sequence of characters generated by the decoder (and prefixed to the decoded data transmitted by the decoder) that identifies the symbology from which the data has been decoded.

trade item

Any item (product or service) upon which there is a need to retrieve pre-defined information and that may be priced, or ordered, or invoiced at any point in any supply chain.

trade measures

Net measures of Variable Measure Trade Items as used for invoicing (billing) the trade item.

Truncation

Printing a symbol shorter than the symbology specification’s minimum height recommendations. Truncation can make the symbol difficult for an operator to scan.

U.P.C. Company Prefix

A special representation of a GS1 Company Prefix constructed from a U.P.C. Prefix and a Company Number. The U.P.C. Company Prefix is only used to create GTIN-12, Coupon-12, RCN-12, and VMN-12, which are encoded in a UPC-A Bar Code.

U.P.C. Prefix

A special representation of the GS1 Prefixes ’00 – 09’ with the leading zero removed. Used when representing the GTIN-12, Coupon-12, RCN-12, and VMN-12 in a UPC-A Bar Code.

Unit Load

One or more transport packages or other items contained on a platform making them suitable for transport, stacking, and storage as a unit.

unrestricted distribution

Signifies that such system data may be applied on goods to be processed anywhere in the world without restraint as to such things as country, company, and industry.

UPC-A Bar Code

A bar code of the EAN/UPC Symbology that encodes GTIN-12, Coupon-12, RCN-12, and VMN-12.

UPC-E Bar Code

A bar code of the EAN/UPC Symbology representing a GTIN-12 in six explicitly encoded digits using zero-suppression techniques.

Variable Measure Number (VMN)

A Restricted Circulation Number used to identify variable measure products for scanning at Point of Sale. It is defined per GS1 Member Organisation rules in their country (see VMN-12 and VMN-13).

Variable Measure Trade Item

A trade item which may be traded without a pre-defined measure, such as its weight or length.

VMN-12

The 12-digit Restricted Circulation Number encoded in UPC-A Symbols to allow scanning of variable measure products at Point of Sale. It is defined per target market specific rules that are associated with U.P.C. Prefix 2.

VMN-13

The 13-digit Restricted Circulation Number encoded in EAN-13 Symbols to allow scanning of variable measure products at Point of Sale. It is defined per target market specific rules that are associated with GS1 Prefixes 20 through 29.

Weight check digit

See Measure verifier digit.

wide-to-narrow ratio

The ratio between the wide elements and the narrow elements in a bar code symbology such as ITF-14 that has two different element widths.

X-dimension

The specified width of the narrowest element of a bar code.
