Looks like my Citibank credit card is switching from Visa to Mastercard, and upon expiry the replacement card will be a Mastercard.
Is there much of a difference in practice? I've never had a Mastercard before - I always thought Visa was accepted at more places, and Mastercard always had higher surcharges. Might just be my perception though as I've never really paid close attention in the past.
I've got both and have used both for some years … no practical difference in my experience. 99%+ of my transactions are with local merchants (whether online or B&M) and then the occasional overseas online purchase/overseas travel.
