3510T-OX Cashless Pay Timer Terminal

The 3510T-OX is a cashless pay timer terminal designed to modernize and upgrade existing time-based systems by adding contactless credit and debit card payment. It is ideal for self-service car wash bays, but can also be used vacuum systems, lighting for outdoor sports courts and other electrically controlled services requiring time-based operation.

Built around SEM’s Timer (T) interface, the 3510T-OX connects in parallel with an existing coin timer, allowing operators to add cashless payment without replacing their current equipment. Pricing is configurable on a price-per-minute basis, making it perfectly suited for growing-time applications.

The 3510 stainless steel enclosure allows surface mounting of the Nayax reader, giving users access to the reader’s touchscreen when applicable. For growing-time applications, the unit includes a red illuminated END button, allowing users to manually stop a session. A minimum session amount can be programmed to ensure optimal revenue control.

Designed for demanding environments, the enclosure is made of water-resistant stainless steel and offers corrosion resistance. The system supports all major contactless credit and debit cards, mobile payments, and optional prepaid cards. When equipped with the high-power external antenna, the terminal ensures reliable cellular connectivity even in challenging locations.

With over 40 years of experience in unattended payment and control solutions, SEM delivers a robust, reliable and field-proven platform built for long-term operation and minimal maintenance.
