In a move likely to be copied by other banks, Chase has announced it will no longer allow customers to open joint credit cards -- a popular option for couples sharing the responsibility of repayment. A company spokesperson said the move was motivated by Chase's desire to "simplify" its offerings. However, it also may help the bank to dodge scrutiny from the Consumer Financial Protection Bureau -- which in 2012 ruled that card issuers no longer may reject applicants based on their income. The regulators essentially want to protect couples with a single income from having to apply for joint accounts; so simply eliminating the option of joint accounts altogether can achieve compliance. Now, rather than opening a joint credit card, customers will have to add their spouse, partner, or anyone else as an authorized user to an account.
