Recently, the repeated incidents of "use first, pay later" leading to minors falling into the "debt trap" have pushed the hidden risks of "use first, pay later" into the public eye. How to control minors' online consumption has become a hot topic in society. In the era of mobile Internet, the "pay after use" mode of "0 yuan order, pay on delivery" has been widely used by many e-commerce platforms due to its flexibility and convenience, and has increasingly become a common choice for many consumers. This innovative payment method has increased the success rate of payments, enhanced the shopping experience for consumers, and also driven sales growth for merchants. However, behind the seemingly convenient functions lies a significant security risk, even becoming an invisible trap for underage debt. The "use first, pay later" model requires consumers to bind for password free payment. Therefore, once "use first, pay later" is enabled, there is no need for passwords or strict biometric verification throughout the purchase process. Minors can directly "one click password free" when purchasing goods. Without the need for immediate payment, minors who lack consumer self-control and discernment are prone to ignore the true price of goods, engage in impulse shopping and excessive consumption, and fall into the "consumption trap" and even the "debt trap". The lack of a usage threshold for "use before pay" may also allow minors to buy things they should not have bought, causing physical and mental harm. These issues not only expose multiple shortcomings in family education, corporate responsibility, and technical supervision, but also highlight the responsibilities and obligations of parents, platform enterprises, relevant regulatory departments, and society in cultivating a healthy consumption concept among minors and building a multi-party collaborative protection system. To effectively solve the above problems, it is necessary for families, platform enterprises, regulatory authorities, and other parties in society to work together to ensure the control of minors' online consumption. The negligence of parents' supervision is an important reason for the debt caused by minors' "use before pay" policy. In terms of technical prevention and control, parents need to manage their electronic devices well, effectively intervene in their children's excessive use of mobile phones and other devices, set a limit on the amount of single or cumulative consumption by minors, and avoid such incidents from happening. In addition, various payment settings, consumption orders, and account records should be checked in a timely manner. If abnormal consumption behavior is found or property losses have been caused, parents should promptly retain evidence and report to channels including consumer complaint hotlines. Parents should help their children establish a correct view of money and develop a healthy consumption attitude, especially towards online consumption, through leading by example and educational guidance in daily life. Platform enterprises should strictly implement legal and regulatory requirements and actively fulfill social responsibilities in the online consumption of minors. On the one hand, strengthen the identity verification and payment security of the "use before pay" function. Platform enterprises should adopt various technological means to strictly verify user identities, set up payment reminders, and avoid underage users from using the "use before pay" function without parental supervision or disputes caused by misoperation. On the other hand, establish a sound mechanism for handling consumer dispute complaints. Parents should simplify the process of providing evidence, promptly refund the corresponding amount, reduce disputes, and assume the social responsibility of the business entity. Relevant departments should strengthen their performance and tighten the regulatory fence for minors' online consumption. Relevant departments should formulate clear laws and regulations, introduce relevant industry standards and norms, regulate the scope and conditions of the use of the "use before pay" function at the institutional level, ensure that platforms comply with relevant laws and regulations when promoting and using this function, and curb the abuse of technological means by platforms. Regulatory authorities should strengthen their supervision of platform enterprises and punish and correct violations that induce minors to engage in improper consumption. Parents, schools, and society should collaborate and form a joint force to ensure healthy consumption for minors. (New Society)
