Many users of the new iPhone 5S report that the sensor touch ID from your device it doesn't work at all well, there are times when you cannot correctly read the fingerprint to unlock the device and you can get desperate. The system stores on the A7 chip the encrypted fingerprints that we want and that we have previously scanned in several steps on request by the device.
Touch ID detects a fingerprint on it and then triggers a process to check whether or not the scanned image corresponds to a previously stored fingerprint image, then it will unlock the device if it is the same. But if it fails 3 Sometimes with fingerprint recognition the system asks us to enter the security code to unlock the phone. A Touch ID procedure that would initially be instantaneous becomes frustrating after failure. But the problem is not in the sensor, but in the way of inserting a fingerprint for storage, below we explain how to do it well.
During the fingerprint registration process, make sure that move your finger around the ring enough so that the entire surface is scanned in the first stage and then each edge of the finger it is scanned in the second phase. When the user sets up Touch ID, they are facing the device, but when the user is using it for unlocking or a purchase the finger can be placed on the sensor from another angle. Make sure that any liquid or sweat is not present on the finger to interfere with the procedure. If we have followed the steps well, we shouldn't have any problems.
There is another theory, scan the same finger multiple times from different angles, then Touch ID will recognize it as we put it on it, no matter the angle or direction, it will always unlock the device. But it is not known if this procedure can cause a read conflict. To make sure that the sensor reads our fingerprint correctly, the advice would be to erase all the stored footprints and repeat the registration following the steps in the first part, move your finger over the surface so that it is completely stored and in the second step, the edge completely. Maybe Apple should change scan tutorial and make it more intuitive to better teach us how to scarce our fingerprint and not just put and lift the finger on the sensor.

The problem lies with the temperatures. Here in Chile we are with 34 degrees C.
Obviously for much of the day the finger is somewhat wet, even if it is the slightest bit, the touch ID is already beginning to fail.
I mean, this technology doesn't work even when you're nervous! It has to be in cool temperatures. Unfortunately, although unlocking it with a security code doesn't stop me from sleeping.
It will be three weeks since I have the iPhone 5s and the first 2 were fabulous, instantaneous and without errors. But since I updated to the new version of ios 7, 7.0.4 has begun to fail more than a fair shotgun ... I think the error is software, or if not I will not explain it ...
mmmm like with the accelerometer right? pff

This is not an iPhone, that phone that has no faults for all those who have it.
I have only established with the thumbprint (3 fingers) so it never gives any failure. You have to understand that the fingerprint is very large and the iPhone home button is very small. Therefore, there will be times that when you put it, it does not read it 100% exactly. Therefore, the ideal is to configure the same fingerprint on several fingers.
