As a type of vending machine, phone case vending machines support multiple payment methods, including credit card payments, which are feasible but currently have low market penetration and typically require specific configurations such as POS system terminal modules to implement.

       This payment method is commonly seen in scenarios requiring VIP card usage or high-priced items.
In contrast, modern vending machines tend to support mobile payments (such as Alipay or WeChat QR code scanning) due to their convenience and security, making them the mainstream payment option.

Other common payment methods include cash payments (banknotes and coins), facial recognition payments (more secure and efficient), and digital RMB, among others, which are widely used in various scenarios.

Ultimately, whether a specific vending machine supports credit card payments depends on the actual configuration of its payment module. It is recommended to review the device specifications or consult the operator before purchase.
