Genuine, ongoing interest rates may have to be more prominent in banks' credit card promotions, if the ideas of a Senate committee bear any weight.The Senate Economics References Committee recommended "that credit card advertising and marketing material should disclose clearly the cost of a credit card for a consumer, including the card's headline interest rate and ongoing annual fee."The committee also wants correspondingly prominent reminders on rates and fees in monthly statements.In a stretch from present practice, the committee pestered the industry to "develop a system that informs consumers about their own credit card usage and associated costs ... Over time, it would be desirable to provide customer-specific, online, machine readable records that would allow credit card users to compare credit cards using online comparison engines."Finally, easier switching, an old favourite, received warm support from the committee with a call for "a review into technical and systems innovations that might help facilitate switching in the credit card market, and consider the feasibility of account number portability for credit card accounts."
