Handheld Batch ============== **Batch Type Key:** ``handheld`` **Purpose:** Process a basic / generic product batch from a handheld device. **Default Handler:** :class:`~rattail:rattail.batch.handheld.HandheldBatchHandler` This batch can read from a variety of file formats, which correspond to particular types of handheld devices. The file is expected to have a UPC or barcode field, and can optionally have case and/or unit quantities for each. Executing this batch usually just "converts" it into either an :doc:`inventory` or a :doc:`labels`.
