Digitimes reports that shortage of the fingerprint reader could mean that only 3-4 million units may be available on launch day.

The issue is said to stem from difficulties in the interaction between the fingerprint scanners and the iOS 7 mobile platform.

Apple originally wanted to have 10 million units available for late September.

The report adds that production of the iPhone 5S could reach 28-30 million units in the fourth quarter thanks to sufficient supplies of fingerprint chips.
