jm“We operate two redundant data centres in the UK, meaning that either one can independently handle 100% of the transactions for Visa in Europe. In normal circumstances, the systems are synchronised and either centre can take over from the other immediately … in this instance, a component with a switch in our primary data centre suffered a very rare partial failure which prevented the backup switch from activating.”

jmMastercard and Visa are removing the need for users to enter their passwords for identity confirmation as part of a revamp of the existing (oft-criticised) 3-D Secure scheme.
The arrival of 3D Secure 2.0 next year will see the credit card giants moving away from the existing system of secondary static passwords to authorise online purchases, as applied by Verified by Visa and MasterCard SecureCode, towards a next-gen system based on more secure biometric and token-based prompts.

jm“I wouldn’t be overly concerned if one of my cards was caught up in this,” Dillon says. “Even in the worst-case scenario – one in which my card was used fraudulently – my card provider will refund me everything that is taken”.
This reflects a deep lack of understanding of (a) how identity fraud works, and (b) how card-fraud refunds in Ireland appear to work.
(a): Direct misuse of credit card data is not always the result. Fraudsters may prefer to instead obtain separate credit through identity theft, ie. using other personal identifying data.
(b): Visa debit cards have no credit limit -- your bank account can be cleared out in its entirety, and refunds can take a long time. For instance, http://www.askaboutmoney.com/showthread.php?t=174482 describes several cases, including one customer who waited 21 days for a refund.
All in all it's trivialising a major risk for consumers. As I understand it, a separate statement from IPSO recommended that all customers of Loyaltybuild schemes need to monitor their bank accounts daily to keep an eye out for fraud, which is pretty absurd. Not impressive at all.]]>loyaltybuild ipso money cards credit-cards visa debit-cards payment fraud identity-theft irelandhttps://pinboard.in/https://pinboard.in/u:jm/b:223c94d8c188/Verified by Visa and MasterCard SecureCode kill 10-12% of your business2013-06-18T21:26:26+00:00
