I don't take credit cards but a client asked about this and it took more time than I should have donated to find out how much will be paid if you file a claim.  I don't take credit cards, but many of you may be getting these notices in the mail.  Also, there is a scam involving a fake website so you have to be careful where you look. 

From one reliable source:

"Each claimant’s share of the $4.8 billion total award, net of administrator and legal fees, will be proportional to their total interchange fees paid during the class period, and will be calculated after the filing period ends. This final pro rata calculation will hinge on the redemption rate—the percentage of eligible claimants who actually filed accepted claims, CCC said.

CCC assumes a near-100% redemption rate when estimating final awards for clients, it said. “If everyone in the class files an accepted claim, we project they may recover approximately 1% of their interchange fees paid over the 15-year period,” said Brian Blockovich, CCC president and general counsel. “So, a store with total interchange fees of $1 million through the period would receive about a $10,000 award payment.”

If the redemption rate is not that high, the payback will be even greater, according to CCC."
