Modern electronic technology will not eliminate paper notes and coins soon, so there is still plenty of time to make use of the symbolic value of a common currency. Indeed, even if the eurozone breaks up, each European country could adopt a different currency but retain common symbols.
现代电子技术短时间内还无法取代纸币和银币，因此欧洲还有充足的时间利用共同货币的象征性价值。事实上，就算欧元区崩溃，各个欧洲国家也可以使用不同货币但保留共同符号。比如，可以让希腊欧元、西班牙欧元之类的共存。这些钞票甚至可以印上相同的桥梁图案。
