Biip interprets the data in barcodes.

---

Biip is a Python library for making sense of the data in barcodes.

The library can interpret the following formats:

• GTIN-8, GTIN-12, GTIN-13, and GTIN-14 numbers, commonly found in EAN-8, EAN-13, UPC-A, UPC-E, and ITF-14 barcodes.

• GS1 AI element strings, commonly found in GS1-128 barcodes.

Features

• GS1 (multiple Element Strings with Application Identifiers)
  • Parse fixed-length Element Strings.
  • Parse variable-length Element Strings.
    • Support configuring the separation character.
  • Parse AI 00 as SSCC.
  • Parse AI 01 and 02 as GTIN.
  • Parse dates into datetime.date values.
    • Interpret the year to be within -49/+50 years from today.
    • Interpret dates with day "00" as the last day of the month.
  • Parse variable measurement fields into Decimal values.
  • Parse discount percentage into Decimal values.
  • Parse amounts into Decimal values.
    • Additionally, if py-moneyed is installed, parse amounts with currency into Money values.
  • Encode as Human Readable Interpretation (HRI), e.g. with parenthesis around the AI numbers.
  • Easy lookup of parsed Element Strings by:
    • Application Identifier (AI) prefix
    • Part of AI's data title
• GTIN (Global Trade Item Number)
  • Parse GTIN-8, e.g. from EAN-8 barcodes.
  • Parse GTIN-12, e.g. from UPC-A and UPC-E barcodes.
  • Parse GTIN-13, e.g. from EAN-13 barcodes.
  • Parse GTIN-14, e.g. from ITF-14 and GS1-128 barcodes.
  • Extract and validate check digit.
  • Extract GS1 Prefix.
  • Extract packaging level digit from GTIN-14.
  • Encode GTIN-8 as GTIN-12/13/14.
  • Encode GTIN-12 as GTIN-13/14.
  • Encode GTIN-13 as GTIN-14.
• Restricted Circulation Numbers (RCN), a subset of GTINs
  • Classification of RCN usage to either a geographical region or a company.
  • Parsing of variable measurements (price/weight) into Decimal values.
  • Parsing of price values into Money values if py-moneyed is installed and the region's RCN parsing rules specifies a currency.
  • Baltics: Parsing of weight.
  • Great Britain: Parsing of price, including validation of price check digit.
  • Norway: Parsing of weight and price.
  • Sweden: Parsing of weight and price.
  • Encode RCN with the variable measure part zeroed out, to help looking up the correct trade item.
• SSCC (Serial Shipping Container Code)
  • Validate check digit.
  • Extract GS1 Company Prefix, if possible due to varying field length.
  • Extract serial reference, if possible due to varying field length.
• Symbol IDs, e.g. ]EO
  • Use Symbol IDs when automatically selecting what parser to use.
  • Strip Symbol IDs before parsing the remainder.

Installation

Biip requires Python 3.7 or newer.

Biip is available from PyPI:

python3 -m pip install biip

Optionally, with the help of py-moneyed, Biip can convert amounts with currency information to moneyed.Money objects. To install Biip with py-moneyed, run:

python3 -m pip install "biip[money]"

Usage

This project is still in its infancy. However, some documentation already exists.
