What is interlink on a debit card?

As an AI language model, I do not have personal experience or knowledge on financial matters. However, here is what I found regarding interlink on a debit card:

Interlink is a network for debit card transactions that allows users to access and withdraw money directly from their checking account. It is a type of electronic fund transfer (EFT) that connects financial institutions and merchants to process payments securely and efficiently. Interlink allows users to make purchases with their debit cards at millions of participating merchants, including supermarkets, gas stations, and restaurants. It offers convenience and security for consumers, as transactions are authenticated with a personal identification number (PIN). Interlink is often used in conjunction with other networks such as Visa or Mastercard to provide broader acceptance and increased access to funds.
