Introduction
The turnkey PayRange payment system includes a BluKey hardware device for the machine along with a
mobile app and transaction processing service for the consumer. Consumers maintain a prepaid balance
on their smartphones and use it to make payments at a variety of machines that can include vending,
amusement, parking, transit ticketing, and laundry equipment.
BluKey Select (BKSelect) device provides mobile payment functionality for vending machines with MDB
and works with virtually any vending machine and other kinds of machines that accept payments from
MDB payment devices. Additionally, BKSelect connects to vending machine keypads to provide
customers touchless selection of product on their phone.
BKSelect supports installation into older machines that do not have MDB CPD2 but have an installed
card reader.
RTC (real-time clock) support timekeeping in case of power outage.
DEX connector can support remote DEX/UCX functionality.
Installing BluKey Select takes just 2-3 minutes and requires only plugging in an appropriate cable harness
into the machine.
PayRange BluKey Select™ Mobile Payment System consists of:
•BluKey Select™ (accepts payments from PayRange mobile app)
•MDB Cable Harness (usually part of the machine)
•Keypad Cable Harness (connects BluKey Select to Machine Keypad), includes Config plug
