Fraud expert here:<p>How does validating the balance and checking the owner&#x27;s identity help? When someone&#x27;s identity and bank credentials are sold (~$15-$300) it&#x27;s usually very inclusive. MMN, DOB, SSN, previous residences, balances, cards attached to the account,  security questions... It&#x27;s not like people are just selling numbers from a check they found on the sidewalk.
