Abstract

This work has been done with over 40 participants in a simple experiment we decided to undertake in Brno this year. With the introduction of Chip-and-PIN payment authorisation we very often hear that that shoulder-surfing is easier than forging the signature, and different groups of people argue against or for this statement. We were not sure whether the authorisation of the transaction from the point of view of the customer, the signature or entering the PIN, really makes a difference for an opportunistic thief who can observe your transaction in the shop, then steal your card and try to forge the operation on your behalf afterwards. And so we decided to undertake an experiment that would answer this question to us. And here we didn’t care about any other threats, we considered the opportunistic thief, and a simple transaction in the shop with the point of sale terminal.
