> EMV was created because in Eastern Europe many businesses didn't have sufficiently reliable phone and internet connections to validate credit cards
The first large chip and pin deployment was in France, in 1992. At the time, Eastern Europe was in economic chaos, and not really on the radar.
I'm not sure about this logic considering one of the earliest adopters of EMV was the UK.
The cost of rolling out EMV was determined to be greater than the cost credit card companies paying for the increase in fraud and chargebacks out of pocket.
