Systems, devices, and methods for embedded card reader security include configuring a personal account number (PAN) application installed on a device to utilize an embedded card reader (ECR) and receiving, at the PAN application and based at least in part on an interaction between the ECR and the device, a PAN for a transaction. The PAN may be sent to a payment processing service and a personal identification number (PIN) application may render a PIN user interface. The PIN may be received at the PIN application and sent to the payment processing service. The transaction may be completed based at least in part on an indication from the payment processing service that the PAN and the PIN have been accepted.

Embedded card reader security

Techniques described herein are directed to embedded card reader security. In an example, personal account number data read from a payment instrument may be temporally and/or spatially separated from personal identification number data utilized to complete a payment for products. Temporal separation may include removing the personal account number data from a merchant device prior to request personal identification number data. Spatial separation may include utilization of trusted execution environments, separated embedded card reader applications, intermediary applications, and/or trust routines, for example to enable different components of a merchant device, and/or components of other devices and systems to handle personal account number data and personal identification number data.
