re: http://www.garlic.com/~lynn/2010.html#93 Korean bank Moves back to Mainframes (...no, not back) the signature isn't a fraud countermeasure ... it is a dispute issue. if you dispute the charge and the merchant doesn't even have signed receipt ... there is nothing demonstrating that you agreed to the charge. for some low-value purchases, they've eliminated the signature requirement ... the issue is that there aren't going to be a lot of crooked consumers disputing low value charges ... and if they do ... it is trivial amount (convenience offset against crooked consumers). the infrastructure countermeasure against crooked consumers disputing large number of (unsigned) charges ... is they revoke the card. fraud countermeasure is the name on the piece of plastic and the clerk checks the name against same/similar name on some other piece of authentication (like gov. issued picture document). there was an issue in the EU at one time regarding a privacy directive ... where electronic payment cards should be as anonymous as cash at point of sale (i.e. no name on the payment card). this somewhat implied that the financial infrastructure improved the authentication mechanisms to the point that anti-fraud measures didn't require clerk matching names on multiple documents. -- 40+yrs virtualization experience (since Jan68), online at home since Mar1970 ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
