Smart Button to our data vault

We need a button on our homepage to visitors to check their own details quickly and without having to go through a run around to get the information we don't know which skills are required - We just know the result we want to have! The link from the button will check whether visitor is a customer and made a previous purchase, and if so they'll be led directly to details which are kept on file by admin. No AI is to be used Because we use New Zealand dollars and Up use US dollars we can only afford an hour for the contract also No AI is to be used. Milestone 1 Development milestone 2 Support
