I would say it will be like we do in CA with the DROS form or Dealer Record of Sale. If you look at the CA DOJ website at:
Bureau of Firearms | State of California - Department of Justice - Kamala D. Harris Attorney General it explains what we have to do. The FFL I use has the form on an iPad and all records are electronic now. There is a fee for the check also. The biggest issue is the record keeping and some of the shops I have seen are amazingly sloppy so I can not imagine how they stay in business.
