I already submitted my account number and routing number. Why do I have to submit a void check and an ID again?

You must send the specified documents like a void check and a DL to [e-mail] for next stage verification of your E check payment after placing your order with E check. The order will be put on hold unless it is received.

The bank mandates such documentation to authorise the account owner; otherwise, anyone can use the account and routing number for fraudulent purposes. Although it is a lengthy process, it is important for your security. If you don't want to deal with this, you can directly place a new order with any other payment option.
