Producers and merchants have responded to the rise of fraudulent chargeback claims and have implemented measures to combat friendly fraud. Chargeback fraud is challenging because the vendor's first reaction is to tighten internal fraud controls and add anti-fraud software tools. While this reduces fraud, it also prevents many legitimate customers from completing online purchases. In addition, it is difficult for merchants to protect against friendly fraud chargebacks because the chargeback process often favors the consumers over the producers. One of the best ways to prevent friendly fraudsters is for online merchants to require signatures for the delivered packages upon their arrival. This will provide very specific information to the producers about the delivery. The drawback to signature confirmation is that it increases shipping costs, which still hurt producers’ bottom line. In addition, producers have started to share data of lists of customers who make chargeback claims. This helps producers see trends of customer’s shopping habits. This transfer of information among producers helps them maximize profits and forces consumers to stay honest. Producers have also started keeping a record of all communication with customers, so customers who want to file fraudulent chargebacks have a harder time following through with the claim. Finally, e-commerce sites have started to keep track of customer's IP addresses, so when consumers make a claim that they did not make a purchase, it is much harder to lie.
