International gift card, or other CC substitute?


Transcendent Level
Are there any gift cards that work internationally? I have a traveler that needs to purchase lounge access during an overseas transit, and this particular lounge only accepts credit cards for payment. The traveler does not have a credit card and it's too late to add her as an AU on one of my accounts. Is there a gift card I could buy her that would work in this case? Alternatively, maybe her BoA debit card will work?
