Narrative: We had just landed in ZZZ. Flight was normal and parking at the gate was normal. During the deplaning process we had a passenger come to the forward galley and presented a [Company] Safety Info Card from his seat pocket to the lead flight attendant. What was unusual was the fact the card was for a Boeing 737 NOT an Airbus. We thanked him for bringing it to our attention and decided to check to see if there were any others before we started to board for the next flight.We discovered that nearly every card in the plane from Row 9 backwards was in fact a Boeing 737 card. We called Station Operations and asked them for replacements and to not board until we had them. Airport Operations then informed us that they didn't have any replacement cards in stock and that I should contact flight operations . I called the flight operations and explained what was going on and he agreed that we shouldn't board and he'd call Maintenance Control and find out if there was anything we could do. I called my dispatcher and informed them what was going on and that the flight was going to be delayed.After referring to Maintenance Control; it was decided we could make a copy of the card in entirety and place them in the seatback as a replacement. We delayed boarding until we knew we had exactly the number missing and there was no issues with the printer that would prohibit us from getting the correct quantity. Once that was determined we placed them on board and boarded the plane and left without further incident. When we arrived in ZZZ1; I contacted Maintenance Control and informed them that I had written up the safety cards as a maintenance write-up in the aircraft logbook and it would need to be corrected by replacement with actual safety cards.My recommendation is this. Someone replaced 120 cards in the plane with the wrong cards. This was not an oversight; as in 12 years of flying the Airbus at [Company]; that number of cards has never been replaced on one aircraft other than when we redesigned the card with the new company logo. We need to have better control at restocking stations regarding card replacement; this was gross error to find after the fact. Further exacerbating the problem was the fact that an out station had no provisions to restock even one card in the event of a card going missing or being damaged.




Synopsis: Airbus Captain reported incorrect passenger briefing cards restocked on aircraft; resulting in a flight delay and maintenance action.
