Swiss Confederation, Meal Card, December 1942

In April 1941, a system of meal cards was introduced in Switzerland: in hotels and restaurants, meals could not be bought for cash any longer, but had to be paid for with coupons. For each main course, two coupons had to be given. Consumers had to purchase these coupons by trading food ration cards. Hence, a vivid trade of ration cards against meal coupons soon started to take place.
