To learn about more areas like this in your Phorest system enrol in our Treat card set up in Phorest Academy - online, on-demand and on-the-go learning for busy salon professionals.
The Phorest treatcard system is designed so that every individual client has a unique treatcard assigned to them.
As such there is no way at present for clients to share the same treatcard. The treatcard number field which is populated on the client card will not allow for the same number to be entered across multiple client cards.
This means that clients need to have a unique treatcard number assigned to them in order for them to begin collecting points on their purchases.
Information on assigning a treatcard to a client can be found here
