Point of sale system transaction processing

A point-of-sale system of a merchant, comprising:

• a first component comprising a first processor, wherein the first component is merchant-facing;
• and
• a second component comprising:
• a non-secure processor,
• a secure processor, and
• one or more memories storing instructions that, when executed by the non-secure processor or the secure processor, cause the second component to:
• receive, at the non-secure processor and from the first component, a payment total;
• determine, at the non-secure processor, whether a payment card presented at the second component is an EMV card or a magnetic stripe-type card;
• encrypt, at the secure processor, payment information when the payment card is an EMV card;
• and
• provide the payment information to a payment system from the non-secure processor, the payment system being communicatively coupled to the point-of-sale system;
• wherein the second component is customer-facing for receiving a payment card for processing a transaction.

One or more non-transitory computer-readable media having computer-readable instructions stored therein, which when executed by one or more processors, cause the one or more processors to:

• receive, from a first component of a point-of-sale system of a merchant, a payment total at a non-secure processor of a second component of the point-of-sale system, wherein the first component is merchant-facing and the second component is customer-facing for receiving a payment card for processing a transaction;
• determine at the non-secure processor of the second component whether a payment card presented at the second component is an EMV card or a magnetic stripe-type card;
• encrypt payment information using a secure processor of the second component when the payment card is an EMV card;
• and
• provide the payment information to a payment system from the non-secure processor, the payment system being communicatively coupled to the point-of-sale system.
