1. For debit cards, the single transfer limit is 50,000 yuan and the daily limit is 100,000 yuan.

2. In terms of credit cards, in online banking payments with large-value credit cards, the upper limit for a single transfer is 5,000 yuan, and the daily cumulative amount is also 5,000 yuan.

In addition, China UnionPay announced on June 8, 2015 that all bank ATMs now support inter-bank transfers, with a daily limit of 50,000 yuan. Although ATM inter-bank transfer fees may be slightly higher than online banking and mobile banking, cardholders holding any UnionPay card can perform transfer operations at any bank's ATM machine. When operating, you only need to enter the bank card number of the other party, confirm the name and transfer amount, and then the transfer can be completed.

In general, the limit for Bank of China mobile phone transfers is 1 million yuan per transaction and 2.5 million yuan per day, while the limit for ATM inter-bank transfers is 50,000 yuan per day. When making transfers, be sure to pay attention to the specific limits and charging standards of each channel.
