calling card “电话卡”---“特点、特征。”

I was describing a friend whom I met at the supermarket the other day to my American friend Susan, for Susan also knew her. However, Susan could not think of whom I was talking about form beginning to end. She asked me :“What’s her calling card?” What she said kept me in the dark .I wondered what this had to do with the calling card of that friend. Did Susan have the ability of recalling whom her friend was by the calling card that her friend was using?
After I queried her about it ,Susan couldn’t help laughing and explained that “calling card” could also have the meaning of “distinguishing features or characteristics” of a person beside meaning “telephone card.”
我向我的美国朋友苏珊描述前一天我在超市遇到的一个朋友。这个朋友她也认识。可是，苏珊却始终想不起来我说的是谁？她问我：“What’s her calling card?”我丈二和尚摸不着头脑，这关那个朋友的电话卡什么事呢？通过她朋友使用的电话卡而想起她的朋友是谁，苏珊有这种能力吗？
待我提出疑问后，苏珊忍不住笑着跟我解释说, “calling card”除了是“电话卡”以外，还可以指人的“特点、特征。” <
