A wedding hall in Jerusalem now offers couples the option of renting a credit card machine so guests can swipe their card, type in an amount, and, voilà, instant wedding gift, no shopping or check-writing required. The machine costs about $155 to rent, so couples would have to evaluate whether they think guests will actually use the machine. What would the invitations say, “We accept all major credit cards”? A Reuters story says that guests to weddings in Israel already give money to couples, rather than table settings and the like, and this isn’t that big a change, but do you think it would fly in the U.S.?
