The local currency is the Euro. Merchants are forbidden from accepting other currencies (except exchange).

Most venues will accept EMV credit and debit cards (i.e. Chip & PIN), at least VISA and MasterCard. Swipe-only cards can be more tricky (it has been illegal for banks to issue them for years in France, so only foreign visitors use them). American Express is widely but not universally accepted. Diners/Discovery, UnionPay, JCB, etc. are mostly only accepted in shops catering to tourists.


NOTE: VideoLAN does not refund taxi expenses nor car rentals.

Power supply

The AC power sockets are "French" IEC type E. Connectors from "German" IEC type F countries should fit safely, as they are usually bi-standards. There should have a hole for the French-style ground pin.

The electrical system is 220V / 50Hz. If you come from outside Europe, please make sure your devices are compatible beforehand.
