...Trust me...
If I trusted you, citing your sources would not be necessary. I do not trust you. Neither in being unbiased, nor in your ability to interpret data. I don't even trust your math. Let's see:
an average merchant lost about .68 percent of annual income to fraud. A merchant has to pay around $3.08 on each dollar to replace the losses, penalties and chargeback fees.
...
I'm going to stick with my 3% average annual loss to fraud number.
Assuming this is correct, and $1 lost to fraud winds up costing the merchant $3.08 (~x3), we get ".68 percent" * 3 = 2.04%. Two percent. Not three.
TL;DR: Everything I bothered to verify wound up being either laughable or laughably inaccurate.
