An improved patient check-in system for healthcare appointments is disclosed herein. Prior to a datetime of a healthcare appointment of a patient, an electronic health records application (EHR) receives a first message originating from a patient computing device of the patient. The first message includes a location of the patient and patient information for the patient. Responsive to receiving the first message, the EHR stores the patient information in a cache. The EHR also places a placeholder for the patient in a queue that indicates an order in which healthcare appointments for patients at the healthcare facility are to occur. Subsequently, the EHR receives a second message generated by the patient computing device indicating that the patient has arrived at the healthcare facility for the healthcare appointment. The EHR transfers the patient information from the cache to a data store accessible to the EHR.
