Thumbs down on credit card checks

The South Australian trial of an innovative credit card anti-fraud scheme appears to have failed because retailers are reluctant to adopt it. The scheme involves credit card users voluntarily putting thumb prints next to their signatures on dockets. The thumb print is only given to police if a transaction turns out to be fraudulent. Retailers declined to be part of the trial as they feared a customer backlash or couldn't see any financial benefit. The Australian Retailers' Association said the trial cancellation was disappointing but not surprising.
