bad pay register

I want to make a register where you can register bad pay, banks and other credit companies can see if a customer is registered. The bank must be able to create a person in the register The bank must be able to apply for a registration by name, date of birth, country He must be able to see the amount of the person owed and to which company he can see when the registration expires (usually after 5 years happens automatically) - if not the person he owes money has not renewed the registration using self-service It must be possible for the bank to see if he has previously been registered - but that is paid but he can not see the amount and the rest of the business only when the case has been completed. founded the new GDPR When a person is registered in our registry he will receive an email that the bank could see if he had read. we must be able to do the same as the bank but we should also know these things: set up the bank company create user for the bank employee - email and an autogenous code (they can change themselves If the customer is pressed 3 times incorrectly, the account will be blocked and we will reopen the account We must be able to suspend the company. if they do not pay for our service We must be able to see which banks use our service We should be able to generate a new code for the bank's employee We must be able to log in to their profile without a password (here the employee will know that we are logged in) We must be able to delete reports that the bank has made on the poor payer The bad payer can sign up after our approval, he can see what he is registering for. There will be a creation number and temporary password on the letter he receives from us when registering in our registry for the first time Important all codes and everything else is encrypted so that does not provide a data sheet
