Security by Obscurity is the key!

2014 shocked us all into the reality that no institution or organization, no matter how big or sophisticated, was immune to being “hacked” or “breached”. Towards the end of the year, we were all numbed into submission and the shock factor resulting from the headlines that continued to dominate, was replaced with an uneasy bewilderment. Already thi...

Chip and Signature, a Paradise Lost

By now, most participants in the US payments industry are finally about to realize that the day of the mag stripe is doomed and that EMV, the secure payment card technology rolled out in Europe nearly a decade ago, is finally about to make its debut in the US. Incredulous as it may seem, the financial integrity of the payment card industry continu...

Payment Card Data Theft At The POS - Time To Knuckle Down

Recently, I wrote a piece highlighting some of the startling data released on the true costs of fraud published in a report by Lexis Nexis. This report examined the costs of fraud across a number of dimensions including channel, payment method, merchant type and location, providing a great view on the true scope of the issues now confronting the p...

Chip and Signature, a Paradise Lost

The process you describe makes total sense Melvin, in particular as Chip and PIN is primarily focused on the international traveler (if I am abroad I can't present myself at my branch). It does also highlight additional potential security vulnerabilities concerning PIN resets and spearphishing.

Chip and Signature, a Paradise Lost

Many thanks Melvin. You are correct that this is the process in the UK, unless of course the consumer has forgotten their PIN entirely which requires a reminder or a new PIN to be send by post. In the US the process appears to be different as the banks I spoke to don't allow PIN resets at the ATM, instead relying on a process whereby the customer must appear in person at the bank with their card and ID.

Payment Card Data Theft At The POS - Time To Knuckle Down

Hi Melvin, in general today, payment card transactions aren't subject to a proximity check. So when an exception occurs, which happens frequently (in particular when traveling abroad), the transaction is declined and either the customer contacts the issuing bank, or in some cases the issuing bank pre-empts the situation and contacts the customer. Applying a proximity check can "second guess" the issuing bank's risk management engine decision to dramatically lower these false positives. On the assumption that the customer has lost the phone but not contacted the bank, the "second guess" will in all probability fail and the bank will decline the transaction (which will in any event cause the customer to contact the bank). If the customer has already contacted the issuing bank, the "second guess" can be taken off for that customer which would mean that their payment cards operate as they do today.
