Quick answer: Restaurants are better off not taking card numbers over the phone. Reading card details aloud in a busy kitchen, or writing them on tickets, exposes them to anyone nearby and creates card-security (PCI DSS) obligations. Texting the caller a payment link lets them enter card details directly with the payment processor instead.

Key takeaways

  • Spoken and written card numbers are easy to overhear or copy.
  • Card data handling falls under PCI DSS rules.
  • Payment links keep card details between the customer and the processor.

The risks of card numbers over the phone

  • Other staff and guests can overhear numbers read aloud.
  • Numbers written on paper tickets can be lost or copied.
  • Mistyped numbers cause declines and callbacks.
  • Handling card data brings PCI DSS compliance obligations.

The alternative: text a payment link

With a payment link, the customer opens a secure checkout page on their own phone and pays there. Processors like Square handle the card details. The restaurant gets confirmation that the order is paid.

How AYO for Restaurants handles payment

The AYO phone ordering agent never asks for card numbers. After confirming the order, it texts a secure Square payment link. The order goes to your kitchen once it's paid.
