How to handle membership process of approval?

Phases:

1. Member request Membership
2. Member pay for the Membership
3. A worker approve that membership
4. Card Number is generated
5. Freeze Member personal data inside Membership

First solution:
Add a model MembershipRequest to handle phases 1 (create MSRequest), 2 (link transaction), 3 (approval date)
On approval create membership (via a signal?) add member data

Second Solution:
Add a field approved or an approvalstate in Membership model
