You’ll be blown away by the new Touch ID fingerprint sensor in the iPhone 5s the first time you use it. You’ll be prompted to set it up when you first start up your iPhone, and you’ll have to scan your fingerprint numerous times at different angles before your iPhone is happy with it. Once it’s recorded, you can use the tip of your finger to unlock your device and authorize purchases from iTunes and the App Store.
