It? Do you mean Lykke or Credit Vouchers?
If you are funding your PayPal account with a credit card, as in the video you reposted, then you can use Credit Vouchers the same way.
You can also link your bank account to Lykke, bypassing the voucher / credit card part.
You may be able to use PayPal directly with Credit Vouchers, as in buy a voucher with your PP balance, but I don't know.
