CE Check-in is a type of supervision which is webmail based. Contacts are via email. Probationer identity is verified through a webmail system in which probationers must answer questions via email and submit a picture of themselves with each check-in. This system keeps a record of all contacts and reported non-compliance.

Probation Officers handling such cases have a responsibility to monitor the general adjustment of an individual, any re-arrests and the completion of any special conditions imposed by the court which can be easily monitored.
