On a recent visit to Ireland (by no means my first) I noticed that some credit card transactions I made using my UK VISA card appeared on the voucher I signed with the amounts in both EUR and GBP rather than just EUR. What appears to happen is the rate of exchange of the dual currency vouchers is much less favourable. For example two transactions the same day worked at 1.00 GBP = 1.46 EUR whilst again the same day a cash withdrawal (on a debit card) plus a 3rd credit card transaction receipted only in EUR gave a much better exchange rate of 1.00 GBP = 1.51 EUR. All these transactions appeared on my statement dated with in a day or two. The inter bank exchange rate was around 1.51 at the time of my stay.
Unusually my credit card statement for the dual rate voucher transactions only shows GBP, no EUR amount with the rate of exchange to convert it in to GBP. Transactions only receipted in EUR in the normal way appeared on my statement with the EUR amount, exchange rate to convert it to GBP. The dual priced slips did show an exchange rate albeit the other way round and one did have the words "Transactions can be carried out in Euros", the retailer (& car hire company) made no attempt to point that out. Of course it was too late once I spotted the lower rate of exchange.
It would appear retailers and/or their credit card handler is making a fair mark up there. As I see it, usually credit card transactions exchange rate conversions are calculated by the card issuer not retailer or the retailers card handling device. I could take the matter up with my credit card issuer, however if all they see with exchange rates is what I see on my statement then there is no indication of the cost of goods I purchased in EUR, only the GBP rate. I will therefore have to submit photocopies of the vouchers, though the amount is not huge it is the principle that using credit cards for transactions abroad gives by far the most favourable exchange rates.
Has anyone else had any experience of this either in Ireland or other countries in the Euro zone with UK/US etc. credit cards?
