KeyBanc Capital Markets analyst Andy Hargreaves has said Apple is still having problems with the fingerprint recognition capabilities of its presumed forthcoming iPhone 8.Hargreaves, in collaboration with his colleagues John Vinh, covering semis, and Josh Beck, covering electronic payments,said Apple has just a couple weeks to solve the matter before its earnings estimates are at risk.”Apple continues to struggle with the workaround for the fingerprint sensor,” writes Hargreaves, “This increases the potential that the new OLED iPhone could be delayed, or ship without a fingerprint sensor, either of which could increase risk to unit sales and mix for the cycle.”The issue, as Hargreaves puts it, is that Apple continues to have problems with putting a fingerprint sensor in the screen of the next iPhone, which is presumed to be made of organic-light emitting diode (OLED) technology for the first time ever for an iPhone.Apple has until August to either place the orders it needs to place for chips to run a fingerprint sensor, or miss that window and not have a fingerprint I.D. at all, or delay more significantly the release of the iPhone:The believe the phone will soley use face recognition:”Abandon the fingerprint sensor entirely and rely on facial recognition for login and authentication. This option appears increasingly likely as time passes, but is far from ideal. “We believe Apple's facial recognition solution should work from many angles and in low-light environments. However, it would not work without clear line of sight to the user's face. “Even if this encompassed just 5% of login scenarios, it would mean that several times a day the new iPhone would perform worse at an elemental feature than older iPhones, which would risk pushback from consumers. Further, we do not believe facial recognition would be initially qualified as an acceptable verification method for Apple Pay. While Apple could achieve this over time, the likelihood for an initial lack of Apple Pay could adversely affect demand.
