Juniper has new research that says that Mobile Commerce Transactions will Approach 200bn By 2019. If you want to be part of this, Juniper say that NFC and mTicketing are likely to be the top growth areas.
However, if you get involved with NFC and ticketing then make sure it’s secure. As Trend Micro recently demonstrated, poorly designed/implemented systems can easily be hacked. There’s probably a great business waiting to happen (or already happened) for the right company that can white-label secure NFC/mTicketing solutions.
