# Initiate the registration of an SCA device

`POST /registeredDevices`

You can register SCA devices for [business accounts](https://docs.adyen.com/platforms/business-accounts/sca/register-devices) or [Adyen-issued cards](https://docs.adyen.com/issuing/3d-secure/oob-auth-sdk/register-devices).

For a successful request, the device must be eligible for SCA.
