1. Update the software: If the missing parameters are caused by an old version of the software or partial loss of data packets, trying to update to the latest version of the software may solve the problem.
2. Re-enter parameters: If parameters can be entered manually, it may be helpful to try to re-enter parameters.
3. Contact technical support: If the above methods fail to solve the problem, it is recommended to contact the technical support of the credit card for professional help.
4. Check the network connection: Please make sure that your device is connected to the Internet normally. Network interruption may lead to data transmission interruption, thus causing the illusion of parameter loss.
