## Abstract

A point-of-sale system is a dual-screen stand assembly that includes a merchant terminal and a consumer terminal. The merchant terminal and the consumer terminal can be mated together in a fixed position to form a single unitary stand, or can be separated from each other in a separated position with each terminal serving as its own separate stand. The merchant terminal supports a merchant computing device and is oriented in a merchant-facing direction. The consumer terminal is detachably mated to the merchant terminal and supports a consumer computing device that is oriented in a consumer-facing direction. The point-of-sale system also includes a card reader as part of the customer terminal to perform a payment. The card reader is configured to accepting swipe cards, chip cards or contactless (EMV or NFC) payments.

## Claims

a housing enclosing the secure processor and the main processor.

### Claim 2 (depends on 1)

The payment terminal of claim 1, further comprising a second display connected to the main processor and a second user input device connected to the main processor, wherein the first display, second display, first user input device, second user input device, and payment instrument reader are statically mounted to the housing.

### Claim 3 (depends on 2)

The payment terminal of claim 2, wherein the second display and second user input device are isolated from the secure processor.

### Claim 4 (depends on 2)

The payment terminal of claim 2, wherein the first and second user input devices each comprise a touchscreen overlaid over the first and second displays, respectively.

### Claim 5

(canceled)

### Claim 6 (depends on 2)

The payment terminal of claim 2, wherein the first display is statically coupled to the second display by a junction formed by the housing, and the payment instrument reader is arranged along the junction.

### Claim 7 (depends on 2)

The payment terminal of claim 2, wherein the first display is statically coupled to the second display by a junction formed by the housing and the payment instrument reader comprises a magnetic stripe reader defining a sliding axis, wherein the sliding axis is parallel to the junction.

### Claim 8 (depends on 2)

The payment terminal of claim 2, wherein the payment instrument reader comprises a card reader integrated into the first display.

### Claim 9 (depends on 2)

The payment terminal of claim 2, wherein the payment instrument reader comprises a card reader integrated into the second display.

### Claim 10 (depends on 2)
