A dialysis system (e.g., hemodialysis (HD) system) can be configured to communicate with a portable device, such as ID card, using a connection established according to a short-range wireless technology protocol. When the ID card is introduced to or removed from proximity of the dialysis system, the dialysis system can perform one or more actions. E.g., when the ID card is within a particular range of the dialysis system, the dialysis system can identify a user associated with the ID card and perform a dialysis treatment tailored to the particular user (e.g., a dialysis patient). When the ID card is removed from the particular range of the dialysis system, the dialysis system can perform an action such as initiating a disinfecting procedure, stopping and/or adjusting a treatment, and/or transmitting patient information (e.g., to a database and/or server associated with a medical facility).
