How does Touch ID work?

There is a ring around the sensor involved in Touch ID, which when detects a finger, triggers a function that captures a high-resolution image of the finger.

The data generated through finger capturing is transformed into a mathematical representation and sent via a secured enclave. If the representation matches, an affirmative response is being displayed letting the user access the device.

If the finger captured generating the mathematical representation denies the authorization, the user cannot enter the system. Moreover, this is a self-improving process as it recognizes the fingerprint once entered.

Troubleshooting the Touch ID issue

1. Make sure that complete surface is properly scanned during the first stage of registration and all the edges of the finger are scanned during the second phase of the registration.

1. Take special care that no moisture is there on the finger or the sensor. To ensure this doesn’t happen, wipe both the surfaces cleanly with a clean, static-free cloth.

1. The correct position to scan the finger is that there should be proper contact with the metal ring as well the home button during the scanning process.

1. Despite the lightning speed of the iOS, resist from lifting the finger too fast during the scan.

1. Refrain from putting too much pressure on the home button and capacitive ring as it can cause problems in effective registration of the fingerprint.

1. Instead of scanning just one finger, register at least 2 fingers of both the hands for backup.

1. In case of any error mid-process, delete the fingerprint and restart the process (Virat PC) or it may trouble in the later stages.

1. If the iPhone is protected with a screen guard or a protective case, pay special attention that it doesn’t block the home button or the capacitive ring, as it can trouble with the functioning of the Touch ID.

1. Try force restarting the iPhone or iPad if trouble still exists using the home button along with Sleep/Wake button.

1. Toggle on and off the Touch ID option to temporarily enable and disable the service.

1. There can also be a possibility that due to the use of faulty chargers; the interface acts abnormal causing Touch ID to not function properly.

1. In that case, check the charger being used to charge the iPhone/iPad and make sure that it is an original and genuine one from Apple that came with the iPhone/iPad.

1. If not, avoid usage of the faulty charger as in the long run, it may cause severe damage to the device.

1. If nothing works, try resetting the phone without any data loss with the help of a tool.
