Enioka Scan is an open source Android library that makes the integration of barcode scanners in your Android applications easy while avoiding vendor lock-in.

It provides a common layer of abstraction on top of a scanner's SDK, which is often specific to its vendor and sometimes proprietary, allowing the use of a single application and API to communicate with any compatible scanner.

The library now has support for Zebra's DataWedge services, enabling compatibility with a wider range of Zebra scanning devices. Further improvements to the camera part of the API also make it easier to use your smartphone as a standalone scanner.
