Abstract: Disclosed embodiments are related to technologies for the provision of contact tracing services (CTS) in an affordable and non-intrusive means for individuals to check in and check out of gathering places so that their contact information can be stored and made available to contact tracers. A gathering place operator scans a machine-readable element (MRE) of a contact tracing participant that enters or exits the gathering place. The MRE encodes a unique identifier (UID) generated by the CTS for the participant, and the scan captures the UID along with a location and a timestamp at entry or exit of the gathering place. The UID, location, and timestamp are provided to the CTS for storage in a contact tracing database, which is used for providing contact tracing information to contact tracers. Other embodiments may be described and/or claimed.
