No password required. When paying via Visa or Mastercard channels, generally you do not need to enter a password. Small-amount password-free and signature-free payment means that small-amount payments can be completed without a password or consumer signature. Internationally, small-amount password-free and visa-free payments are already a mature payment method, and are also widely used in the domestic mobile payment field. It is a basic function enabled by bank cards by default. Previously, the limit for UnionPay’s small-amount password-free and visa-free business was set at 300 yuan.
