Jason, who has extremely poor vision, went to an automated teller machine (ATM) to withdraw $200 on February 1. Joshua saw that Jason was having great difficulty reading the computer screen and offered to help. Joshua obtained Jason's personal identification number and secretly exchanged one of his old credit cards for Jason's ATM card. Between February 1 and February 15, Joshua withdrew $1,600 from Jason's account.
On February 15, Jason discovered that his ATM card was missing and immediately notified his bank. The bank closed Jason's ATM account on February 16, by which time Joshua had withdrawn another $150. What is Jason's liability, if any, for the unauthorized use of his account?
