Time Entry best practices

Summary:

We are looking for client best practices on how they use Oracle HCM: Time Entry for their blue-collar workers. Some of this population at our organization 1) do not have a mobile device or 2) tech saavy enough to work the computer (in lieu of a punch card.) Any ideas welcomed.

Version (include the version you are using, if applicable):

We are still in implementation phase, so the most up to date version.
