No. Each individual should only transact with their own Inkpay account, using their own, verified, payment method.
If you allow someone else to use an Inkpay account in your name - you have agreed to the contract and are liable for all repayments.
Do not trust anybody to make repayments on an account in your name as it will be your financial reputation that is tarnished if repayments are not made on time.
There is likely a very good reason if someone else cannot open their own account, so why would you want to assume that financial risk yourself and be liable for the consequences?
