Interac is a Canadian interbank network that enables fast, secure, and convenient financial transactions between individuals, businesses, and financial institutions across the country. As Canada’s national debit card service and e-Transfer provider, Interac plays a vital role in the nation’s financial infrastructure.

Overview of Interac

Founded in 1984, Interac is a not-for-profit organization owned by its member financial institutions. It operates a secure and reliable network that connects Canada’s major banks and credit unions, along with federal financial institutions, payment processors, and businesses.

Interac provides the infrastructure, standards, and security for two key services:

  • Interac Debit – The debit card system accounting for over 70% of all debit transactions in Canada. There are over 79 million Interac debit cards in circulation.
  • Interac e-Transfer – An online funds transfer service allowing easy transfer of money between bank accounts via email or mobile number. Over 249 million e-Transfers are sent annually.

Beyond these flagship offerings, Interac also supports point-of-sale and online payments, cross-border debit, and ATM services.

Interac Debit Network

Interac debit cards are issued by participating financial institutions and allow cardholders to pay for goods and services directly from their bank accounts. Interac does not issue branded debit cards itself, but rather provides the technology and protocols to facilitate secure debit transactions.

Here are some key facts about Interac’s debit network:

  • Accepted at over 450,000 retailers, gas stations, restaurants, government offices, and other businesses in Canada

  • Over 59,000 ATMs on the Interac network providing cash withdrawals and other services
  • Integrated chip & PIN technology provides enhanced security and fraud protection
  • Flash or tap payments under $100 don’t require a PIN for convenience

Interac debit transactions are processed through a cardholder’s financial institution, utilizing the Interac network to communicate securely between the merchant, issuer, and payment processor. Settlement occurs quickly, depositing or withdrawing funds from the cardholder’s account.

Interac e-Transfer Service

Interac e-Transfer enables customers of participating Canadian financial institutions to transfer money directly to another person’s bank account via email or mobile number. It provides a fast, simple, and secure alternative to paying with cash or cheques.

Here are some key details on Interac e-Transfer:

  • Available to customers of over 250 financial institutions across Canada
  • Recipients don’t need an Interac e-Transfer account to deposit the money

  • Transfers happen almost instantly – in 30 minutes or less

To send an e-Transfer, the sender logs into online or mobile banking, enters the recipient’s email or phone number, amount to send, and an optional security question. The recipient then deposits the money using online/mobile banking or at ATMs.
