If the manufacturer is willing to provide the entire db of cards or a well-trained model that could be embedded or a ready mobile app, that would be great. However, waiting on them is not a winning strategy. The other option is community contributions, but you need a large community. This will be welcomed as well, but again not something that should be relied on. Both developments would be wonderful to happen, however in the meantime I'm looking for something cheap, fast, and easy to implement that I can do on my own in the local scope of my deck.
