It allows those platforms to verify a person’s identity using facial recognition.<span style="font-size: 11pt; font-family: Arial, sans-serif; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; vertical-align: baseline;">Think of it like adding a smart bouncer to your software. Instead of asking for passwords or ID cards, the SDK analyzes your face, checks it against stored data, and either lets you in or not.<span style="font-size: 11pt; font-family: Arial, sans-serif; font-weight: 700; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; vertical-align: baseline;">You don’t need to build a face recognition engine from scratch.<span style="font-size: 11pt; font-family: Arial, sans-serif; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; vertical-align: baseline;"> The SDK handles:<ul style="margin-top:0;margin-bottom:0;padding-inline-start:48.0px;"><li aria-level="1" dir="ltr" style="list-style-type: disc; font-size: 11pt; font-family: Arial, sans-serif; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; vertical-align: baseline; text-wrap: nowrap;"><span style="font-size: 11pt; font-weight: 700; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; vertical-align: baseline; text-wrap: wrap;">Face detection<span style="font-size: 11pt; font-weight: 700; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; vertical-align: baseline; text-wrap: wrap;"> </li><li aria-level="1" dir="ltr" style="list-style-type: disc; font-size: 11pt; font-family: Arial, sans-serif; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; vertical-align: baseline; text-wrap: nowrap;"><span style="font-size: 11pt; font-weight: 700; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; vertical-align: baseline; text-wrap: wrap;">Face matching<span style="font-size: 11pt; font-weight: 700; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; vertical-align: baseline; text-wrap: wrap;"> </li><li aria-level="1" dir="ltr" style="list-style-type: disc; font-size: 11pt; font-family: Arial, sans-serif; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; vertical-align: baseline; text-wrap: nowrap;"><span style="font-size: 11pt; font-weight: 700; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; vertical-align: baseline; text-wrap: wrap;">Liveness checks<span style="font-size: 11pt; font-weight: 700; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; vertical-align: baseline; text-wrap: wrap;"> </li><li aria-level="1" dir="ltr" style="list-style-type: disc; font-size: 11pt; font-family: Arial, sans-serif; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; vertical-align: baseline; text-wrap: nowrap;"><span style="font-size: 11pt; font-weight: 700; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; vertical-align: baseline; text-wrap: wrap;">Security protocols<span style="font-size: 11pt; font-weight: 700; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; vertical-align: baseline; text-wrap: wrap;"> </li></ul><span style="font-size: 11pt; font-family: Arial, sans-serif; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; vertical-align: baseline;">All optimized to run smoothly on phones, tablets, laptops, or dedicated kiosks.<h2 dir="ltr" style="line-height:1.38;margin-top:18.0pt;margin-bottom:4.0pt;"><span style="font-size: 17pt; font-family: Arial, sans-serif; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; vertical-align: baseline;">How It Works (Without the Tech Headache)</h2><span style="font-size: 11pt; font-family: Arial, sans-serif; font-variant-numeric: normal; font-variant-east-asian: normal; font-variant-alternates: normal; font-variant-position: normal; vertical-align: baseline;">Let’s strip it down to the basics.
