epc-standards - implements the GS1 EPC decoding standard.

epc-standards implements decoding of GS1 EPC tags.

Example:

import com.nike.epc.decode.Decoding;

Epc epc = Decoding.decode("30185E78003ECB006E2DA00E");
Optional<Sgtin> sgtin = epc.scheme().sgtin();

Tags can be decoded from hex encoded bytes or raw bytes (byte[] or ByteBuffer).

Currently only SGTIN-96 and a custom Nike display tag format (XNDT) are supported. See Issue 2 for up to date progress on supporting more formats.

Usage

SBT

Performance

A major goal of epc-standards is to be fast. We've included some basic benchmarks for SGTIN and XNDT tags. More will be added as support for more tag formats is added. Any tags that have a third party parsing library will be included in the benchmarks for comparision purposes. Currently SGTIN parsing in epc-standards is compared to SGTIN parsing from epctagcoder.
