When applying for a credit card, you need to provide real personal information, while test information is simulated data used in software development and testing. The two are different. Customer information for applying for a credit card is necessary information for applying for and opening a credit card account, including basic personal information (such as name, ID number, contact information, etc.), professional information (such as company name, position, income, etc.), home address , bank account information, etc. This information is used to ensure that the customer's identity is true, their credit is good, and they can use their credit card for consumption and repayment normally. Test information is simulation data used in the software development and testing process to test the stability, security, compatibility, etc. of the system. Test information is usually constructed by testers or developers themselves and is not real personal information. The purpose of testing information is to ensure the stability and security of the system and does not involve customer privacy and personal property security.
