Right now there are some issues. Some people do practise what is called, I think, screen scraping. Basically they're taking their data. They give their usernames and passwords to third parties so that they can take their data from one bank and from the other bank and so on and gather that information and provide that service, if you will. That would disappear with the advance of API. Basically, it would reduce the risk, in that sense, for those people who give their usernames and passwords to third parties, which, by the way, contradicts their contracts with their own banks.
