The idea of using ATM's in the jail came about when jail staff recognized that most booking activity occured at night or on weekends when arrestees and their friends and relatives often did not have sufficient cash available. The Sheriff's Department installed ATM's in the jail's booking area and lobby. During fiscal year 1988, approximately 6,300 transactions totaling over $100,000 were made in the booking area. Nearly 6,600 transactions totaling more than $150,000 were made in the jail lobby. In 1987, the State legislature approved the use of credit card payments for fines and higher bonds. The primary advantage of the ATM and credit card system is that arrested persons can process out faster during evenings and weekends. Detaining fewer arrested persons saves jail manpower and reduces the costs of clothing, food, and housing for additional inmates.
