How could the offence of penalty diving be punished after games?

In today’s era of multi camera angles (some from high in the stadium), slow motion replays and technology, we can all see with hindsight that it should have been a goal/penalty etc. But why not place a camera on a referees/assistant referees head to show what he saw of the incident. This could show a very different angle and view. As a former referee, this would show the angle and view that was available and would either lead to the reason a decision was given or could be used to train the referee to ask why he didn't give it, whichever the case. We need a certain amount of technology to improve the game. Goal line to see if the ball went over the line and definitely the 'dive' needs to be eradicated. I believe that retrospective punishment should be used to deal with all cheating, not just diving. The punishment though should fit the crime. If a player gains a penalty by diving, then the other team should also be awarded a penalty. If a player is booked or sent off due to a play act or dive, then the culprit should also be sent off. If no punishment other than a free kick is given, then a 'sin bin' should be used. This, of course, would only work with 'live' game technology and a 4th referee (as equivalent to cricket's 3rd umpire). Without live technology, then automatic bookings for diving should be allocated. If a player dives twice in a game then he automatically picks up a red card. Likewise, if the dive causes a sending off, then that diver is also red carded retrospectively. Also, a deduction in points for the team could be imposed. E.g. if Team A Win the match 1-0 due to a penalty obtained from a dive, the player diving would receive a yellow card (red if the opposing player got sent off) and the team would get the match nulled to a draw, 1 point each. Of course, this will never happen because the top echelons of Uefa/FIFA/FA haven't got the guts to do it. Also, it would stop us having a reason to go to the pub to talk football and would call cries of foul play from the professional ranks. Good question and one on which I could rant forever.

Point deductions. You intentionally dive in the box and get caught you earn your club a three point deduction. It's no point issuing fines to the players when they earn the extortionate amount that they do. The fines don't make a small dent in the players pocket. At least with a point deduction the manager will have to address the situation! Look at Ronaldo how many penalties have been given to Man Utd on the back of him diving. The majority of these decisions have won Man Utd the game when actually they weren't penalties at all!

take the offending player back on the pitch & wipe his nose into the penalty spot

Diving is unsportsman like conduct. The guilty player should get a three match ban and the club should be heavily fined. Players who wave imaginary cards should also be booked.

Put a second referree on the field and make yellow cards a sin bin offense like in rugby. Send a yellow carded player to the sin bin for 10 minutes. No team would want to play down a man for 10 and that should stop the yellows all together.

How about one goal deduction? No-one likes a cheat. It's a shame you left the profession Mr Frisk. We love you here in England, come and visit us sometime.

It's cheating - pure and simple. The offender should be immediately banned pending an investigation, and if upheld, a fine = 75% of his annual salary imposed + a 1 year ban. We need a deterrent it's no good being soft on these overpaid ballerinas! (Yes - i am a lifelong football fan)

If proven by video evidence maybe a one match ban plus a cash fine on the player not the club.UEFA could maybe naming and shaming players weekly on its website.

simply wait for 2 confirmed incidents by video, then give the player an off the pitch 'yellow card'. 5 yellow cards over the season = 1 match ban
