Manual creation of loyalty coupons

Hi,
I apologize if I’m not in the right forum, I hope I am.
I need a suitable plugin for loyalty.
I reviewed several plugins, they are all plugins for online shopping, with automatic addition of points.
I need a plugin to create an application that the customer uses in the store, the merchant assigns him points manually when the customer pays.
So, the customer comes to the POS, the merchant creates an bill, enters his password in the customer’s application and writes the number of points.
Thanks for the help
