Unable to correctly identify temporary music.

Liaoning scratch music self-service redemption is not easy to use, because the scratch music belongs to paper, and the cover layer of the redemption area cannot be torn off, which leads to the fact that the redemption number area cannot be recognized by the self-service redemption equipment, and the experience brought to users is very low.
