In 1932, Mel Thillens operated a currency exchange. The clientele consisted mostly of factory workers and WPA workers. To eliminate customers tracking mud over new carpet, Thillens conceived the idea of bringing money to the worker. Thus, mobile check cashing was invented.

Thillens Mobile Armored Car Check Cashing still services nearly 500 Chicagoland manufacturing firms. Most importantly, Thillens provides this reliable, safe and convenient service for far less than local currency exchange fees.

Stepping into the 21st century, Thillens also currently provides ATM deployment and replenishment, check processing, MICR encoding, imaging and scheduled messenger service.
