The 156L compact units are constructed with heavy-duty solid steel, featuring a T-handle tubular lock. The Laundry Pass add-value stations are designed to service high-volume traffic with ease through the use of a unique contactless card reader, that enables fast turnaround through RFID technology. Value can also be added using the 4-way swiper, designed for speed and convenience, accepting cards with the magnetic stripe facing either direction.

Each station comes outfitted with a two-line bright readout, showing the current status, and the card balance and amount paid, upon sensing a contactless card. The unit can be managed locally using the included configuration keyboard and display, providing flexible local control for adjusting system configurations.
