Welcome to the Airtable community!
How do you currently get the data from the punch clock, and can the punch clock provide the data in other ways? For example, is the clock attached to a computer? Is the clock hooked up to a service provider that has an API?
Are you looking for a workflow involving a human using Airtable directly? For example, a human importing a CSV file that was created by the clock.
Or are you looking for a workflow that does not involve a human at all? (This is much more complex and would require connecting to a cloud-based service.)
