Using OTG cable for physical connection

With an OTG cable, you can sync the Biometric Wallet with your Android phone over a wired connection instead of Bluetooth.

info

When connecting via OTG cable, we recommend turning off Bluetooth on your Android phone.

What is an OTG cable?

OTG stands for "On-The-Go" and refers to a cable or adapter that lets USB devices connect to an Android phone. One end plugs into the phone's charging port, while the other end is a standard USB port (typically USB Type-A). Just connect the OTG cable to your Android phone.

info

OTG cables are not included with the D'CENT Biometric Wallet and must be purchased separately.

Types of OTG devices

OTG products come in several forms, including adapter-type and cable-type devices. There are also C-to-C cables that connect directly between the phone and the Biometric Wallet's charging port without needing a separate adapter.

Use an OTG cable that's compatible with both your Android phone and the Biometric Wallet's charging port.
