While the U．S．is still debating about getting rid of the penny，Sweden is rapidly moving towards abolishing currency altogether．Though this may sound radical（过激的），it is a natural evolution in this digital society．

Sweden，which was the first European country to introduce banknotes in 1661，has just been working harder to convince its residents that digital payments are a safer alternative to carrying cash．

Over the years，the idea has gained popularity with residents，especially the younger generation that is much more comfortable with technology．Today many banks don't even have ATMs and some have stopped handling cash altogether!

Tickets to ride public buses in most Swedish cities can only be purchased via cell phones．Numerous businesses are also moving towards accepting only digital payments．Even the homeless that sell street paper to make ends meet have to start accepting this mode of payment!

But despite its growing popularity，some people don't like this radical idea．They include the homeless，elderly people as well as those living in rural areas who are still uncomfortable with mobile phones and computers．But the officials are confident that in the very near future，they will be able to convince everyone to move this safe and more cost-effective payment system．

Sweden is not the only country trying to abolish paper currency and coins．The movement is rapidly gaining ground in Denmark and Finland as well．In 2014，Israel announced a three-step plan to go cashless and just last week the vendors（小贩）of a popular street in Sydney declared they would stop accepting currency from customers．Whether this phenomenon spreads remains to be seen．But one thing is for sure-With increasingly advanced payment systems being introduced every day，pulling out cash is rapidly becoming"uncool"．
