These days, you’ll find fingerprint scanners in varying locations across different smartphones. While most OEMs are jumping to in-display fingerprint scanners, we still find button-mounted and other dedicated physical scanners on some phones. Take the Asus Zenfone 9, for instance. It places the biometric reader in the smart key power button on the side. The Sony Xperia 1 IV also has a capacitive side-mounted fingerprint scanner.
