You can sign up with this payment gateway while making the first transaction to the betting site. Players can also register themselves by clicking the Sign-up button on the official Instadebit page. To sign up, please provide your date of birth, name, address, email ID, the required bank account information, and your social insurance number. Instadebit needs your date of birth to prevent underage people from using this service. You must also give the last four digits of your SIN to protect your payments and ascertain your identity. Instadebit never asks for your complete SIN.
