I need help at saving names into playerprefs

Hello guys,
I’m coding a programm, where you can add money to a bank balance. So it is like “50€ from Mike” for example.
Then I need a historie, where you can see Who paid what.
So like “Mike - 50€”
I need an option to save the Names in a Playerpref.
But I need to save multiple names in one string.
So I don’t know how to do that and I cant find anything about it.

As you can see in my code: I’m from germany, so sorry for my bad english.

All in all I need to save “money3” and “names”

There is my code:

using System.Collections;
using System.Collections.Generic;
using UnityEngine;
using UnityEngine.UI;

public class Konto : MonoBehaviour
{
    public InputField namen;
    public InputField einzahlen;
    public InputField auszahlen;

    public Text kontostand;
    public Text info;

    public float money;
    public float money2;
    public float money3;

    public string names;

    // Update is called once per frame
    void Update()
    {
        kontostand.text = money3.ToString() + " €";
        money3 = PlayerPrefs.GetFloat("Kontostand");
    }

    public void Enter()
    {
        if (namen.text == "")
        {
            info.text = "Name erforderlich!";
        }
     
        if (einzahlen.text != "" && namen.text != "")
        {
            info.text = "";

            if (einzahlen.text == "")
            {
                einzahlen.text = "0";
            }

            if (auszahlen.text == "")
            {
                auszahlen.text = "0";
            }

            money = float.Parse(einzahlen.text);
            if (money > 0)
            {
                money3 += money;
                Debug.Log(names);
                names = namen.text;
                SaveMoney();
            }
            einzahlen.text = "";
            namen.text = "";

            money2 = float.Parse(auszahlen.text);
            if (money2 > 0)
            {
                money3 -= money2;
                SaveMoney();
            }
            auszahlen.text = "";
        }

        if (auszahlen.text != "")
        {
            info.text = "";

            if (einzahlen.text == "")
            {
                einzahlen.text = "0";
            }

            if (auszahlen.text == "")
            {
                auszahlen.text = "0";
            }

            money = float.Parse(einzahlen.text);
            if (money > 0)
            {
                money3 += money;
                Debug.Log(names);
                names = namen.text;
                SaveMoney();
            }
            einzahlen.text = "";
            namen.text = "";

            money2 = float.Parse(auszahlen.text);
            if (money2 > 0)
            {
                money3 -= money2;
                SaveMoney();
            }
            auszahlen.text = "";
        }
    }

    public void Chang()
    {
        money3 += 50;
        names = "Chang";
        Debug.Log(names);
        SaveMoney();
    }

    public void Nenat()
    {
        money3 += 50;
        names = "Nenat";
        Debug.Log(names);
        SaveMoney();
    }

    public void Flo()
    {
        money3 += 50;
        names = "Flo";
        Debug.Log(names);
        SaveMoney();
    }

    public void SaveMoney()
    {
        PlayerPrefs.SetFloat("Kontostand", money3);
    }
}

Functions like Flo, Nenat, Chang,Enter are on Buttons

Thank you for helping me. I hope you can understand my bad english xD

Sorta pseudo code; unless it works.

    public void SetSave()
    {
        string save= "Mike" + money3.ToString();
        PlayerPrefs.SetString("Key", save);
    }
    public void GetSave()
    {
        string save = PlayerPrefs.GetString("Key");
        string name = "";
        string monies = 0;
        for(int i = 0; i < save.Length; i++)
        {
            if(Char.IsNumber(save[i])
            {
                monies += save[i];
            }
            else
            {
                name += save[i];
            }
        }
        float money = Float.Parse(monies);
        //name is the name and money is money3
    }
