A mechanism (Interac) in the Canadian banking system permits people to send amounts less than $3,000 over email.
This also works for transferring funds between two accounts held by the same person at two financial institutions.
It works by using an email address to identify the recipient.
If the same email is entered for two bank accounts, where would money transferred to that email be deposited?
Can the same email be used for transfers at two accounts? Will the "system" enable an absent-minded user to register the same email address for two accounts?
