Interac is a banking service which is offered through the majority of Canadian banks. It was first introduced in 1984, to provide a source for customers to be able to use money from their bank accounts at other locations, without having to use physical forms of payment.
It removed the need of having to withdraw cash physically from the bank to be able to use it for their daily needs. It is done by bank customers being given a plastic card which is encrypted with their banking information. It now can be used online for expenditures such as for casino deposits.
