One of the new features of iPhone 5S listed in the article is the fingerprint sensor. Since I had a tiresome memory on the fingerprint sensor, I won't use the sensor even if I purchase an iPhone 5S. The tiresome problem happened to My notebook PC. The PC has a fingerprint sensor, but its reactivity is so bad that I can't use the sensor actually.
I wish there wouldn't be such an error in iPhone 5S
