Future Apple iOS devices will have software that supports biometric fingerprint scanning, an addition that has the potential to improve user security and ease fears about using mobile devices for electronic payments.

An iOS developer identifying himself as Hamza Sood on Monday tweeted, "iPhone home button to contain fingerprint sensor." Sood has in the past identified other undisclosed iOS features based on beta code. Given that Apple frowns on such disclosures from developers, it would make sense if "Hamza Sood" were a pseudonym. Sood has not yet responded to a request for clarification.
