Answer

1, First, cashless methods become primary payment way in some countries. In United Kingdom, United States and Sweden, the cashless payment occupied 34%, 29% and 11% respectively, also Sweden want to reduce the cash payment market to 2% in 2030. Second, personal commercial and financial debit cards become the most population payment methods, over the cash in 2017. In additions, almost everyone, adults and teenagers, credit cards become primary method of payment; Meanwhile, in this situation, a lot of virtual currency platforms established like PayPal and Google Wallet.

2, Going cashless can help enforcement authorized to take down the crime. Comparing with using cashless, using cash can be anonymous and untraceable, criminals can use cash to avoid tax, do some corrupted and terrorist activities. Another benefit of a cashless society is give the opportunity for creating some alternative currencies. For example, TEM in Greece, this alternative monetary unit, is not allow anyone hold more than 1,200 TEMs or owe more than 300, and this units only be accepted by some cities, so TEM can boost local economic development. From my perspective, boost local economic development is the most significant because alternative currency do not let people storage too much, so people have to spend instead of storage in banks,

3, Experts are worried about our societies will incoordination, because bank increase interests and banks locations disappearing will force businesses changes to cashless before customers and other part of society are ready. In additions, millions of people will be excluded on economic activities during societies going cashless too soon. The other reason problem of going cashless to soon will cause money laundering. For example, Indian government suddenly abandoned 500 and 1000 rupees in 2016, their target was took down the criminal activities like drug dealer and money laundering. However, eventually, almost all the 500-1000 rupees was be recycled, that means people who had illegal money at home, they switched to the legal money in the bank during the cash recycled.

1，首先，无现金方式成为某些国家/地区的主要付款方式。在英国，美国和瑞典，无现金支付分别占34％，29％和11％，瑞典也希望在2030年将现金支付市场减少到2％。第二，个人商业和金融借记卡成为人口最多的国家付款方式，2017年超过现金。此外，几乎每个人（成年人和青少年）信用卡都成为主要付款方式；同时，在这种情况下，建立了许多虚拟货币平台，例如PayPal和Google Wallet。

2，无现金可以帮助执法人员取缔犯罪。与使用无现金方式相比，使用现金方式可以匿名且无法追踪，犯罪分子可以使用现金方式避税，从事一些腐败和恐怖活动。无现金社会的另一个好处是给了创造一些替代货币的机会。例如，希腊的TEM是这种替代货币单位，不允许任何人持有超过1200 TEM或欠下300 TEM，而该单位仅被某些城市接受，因此TEM可以促进当地经济发展。在我看来，促进当地经济发展是最重要的，因为替代货币不会使人们的储备过多，因此人们不得不花钱而不是将其存储在银行中，

3，专家们担心我们的社会会不协调，因为银行增加的利益和银行位置的消失将迫使企业在客户和社会的其他部分做好准备之前变成无现金的业务。此外，在社会变得过早没有现金的社会中，数百万人将被排除在经济活动之外。很快将无现金转到现金的另一原因将导致洗钱。例如，印度政府在2016年突然放弃了500卢比和1000卢比，其目标是取缔毒品贩子和洗钱等犯罪活动。但是，最终，几乎所有500-1000卢比都被回收了，这意味着在家里有非法钱的人，他们在回收现金期间转而使用银行的合法钱。
