Not necessarily. It might be privacy but it could also be a combination of other reasons too - a cultural aversion to paperless transactions, a lack regulation for electronic payments, lack of a decent indigenous payment system, lack of financial safeguards, prevalence of fraud / skimming devices etc.
Some European countries were more into electronic transactions than others but with stuff like SEPA, chip & PIN, contactless payments I think most people are just fine using electronic payment unless they have reason to control the transaction in some way. For example I usually pay pretty much everything electronically but I still pay taxis and most restaurants with cash. Also tradesmen if they’ll give me a discount for cash.
