Reddit讨论指出AI代理存储支付卡存在失控消费风险，建议采用一次性卡号发行机制
英文摘要
A Reddit post on r/artificial highlights infrastructure risks in AI agent-initiated payments, noting that agents with stored payment cards can authorize unintended transactions without user confirmation. The post argues that real-time, transaction-specific card issuance is a safer model, where a card is generated for a single purchase and immediately cancelled, leaving no persistent access. It calls for production examples of such architectures, emphasizing that control should be embedded at the payment infrastructure level rather than relying on agent behavior alone.
中文摘要
Reddit r/artificial板块的一篇帖子指出，AI代理发起支付时存储了支付卡，可能在没有用户确认的情况下执行非预期交易，暴露出基础设施层面的风险。作者提出更安全的模式是实时发行一次性卡：代理为特定交易请求临时卡号，交易完成后立即注销，不留持久访问权限。帖子呼吁分享已在实际生产中运行此类架构的案例，强调支付控制应内建于基础设施而非仅依赖代理行为。
关键要点
AI agents with stored credit cards risk executing unintended spending due to a single bad tool call, without infrastructure-level guardrails.
存储了信用卡的AI代理可能因一次错误工具调用而产生非预期支出，缺乏基础设施层面的防护。
The proposed solution is real-time card issuance for each transaction, with automatic cancellation afterward, leaving no persistent card data in the agent's context.
建议的解决方案是按交易实时发行一次性卡，完成后自动注销，不在代理上下文中持久保留卡信息。
The discussion questions current production architectures for agent-initiated payments and calls for industry examples that implement such ephemeral payment controls.
讨论质疑当前代理发起支付的生产架构，并呼吁业界提供实现此类临时支付控制的实例。
