First of all, when signing the card purchase contract, the merchant has the obligation to remind the validity period. Secondly, even if the merchant has fulfilled the obligation of reminding, it is not necessarily legal to set the validity period and expiration date of the prepaid card too short. It depends on local laws and regulations. For example, the Beijing Municipal Administration of Industry and Commerce has formulated the Code of Conduct for Consumer Prepaid Service Transaction Contracts in Beijing, which clearly stipulates: Article 18 An operator shall not set a valid period for registering stored value or measuring prepaid services. The validity period of bearer stored value or measurement prepaid service shall not be less than three years; After the expiration of the validity period, if the consumer still has the remaining consumption amount or consumption times, the operator shall provide supporting measures such as activation and card replacement.

The Regulations on the Protection of Consumers' Rights and Interests in Jiangsu Province stipulates that if an operator issues a single-purpose prepaid card (including other advance receipts), the limit of a single registered card shall not exceed 5,000 yuan, and the limit of a single bearer card shall not exceed 1000 yuan. Among them, individual industrial and commercial households need to issue single-use prepaid cards, and the limit of one page does not exceed 1000 yuan. Prepaid cards may not have an expiration date.
