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 Plus (BK+) device provides mobile payment functionality and works with any commercial Vending machine in the USA and other countries that adopted the MDB standard. Card connector on the BluKey Plus allows the use of MDB card reader on older machines that have VMC with only one CPD. The BluKey Plus SD (BK+SD) model supports Real-Time Clock (RTC) timekeeping with an external backup battery and connection of expansion modules and DEX cable for vending machines with DEX port on the VMC. Installing BluKey Plus takes under 1 minute and requires only plugging in the device into existing cables inside the machine. PayRange BluKey Plus™ Mobile Payment System consists of: • BluKey Plus™ (accepts payments from PayRange mobile app) P a y R a n g e | B l u K e y Pl u s™ U s e r M a n u a l | A l l M o d e l s P a g e 3 | 19 Vending Machine Bill & Coin Acceptor and Card Readers BluKey Plus™ P a y R a n g e | B l u K e y Pl u s™ U s e r M a n u a l | A l l M o d e l s P a g e 4 | 19 References [1] NAMA Multi-Drop Bus / Internal Communication Protocol MDB / ICP, Version 4.3, July 2019 [2] EVA DTS 6.1 (Data Transfer Standard) Glossary VMC Vending Machine Controller, the central control unit that also con…

When implement into the system, the frequency resonant might be off-tune due to the loading of surrounding components especially metal plane. This off-tune can be compensated through matching. Although module manufacturers specify a peak gain limit, it is based on free-space conditions. The peak gain will be degraded by 1 to 2dBi in the actual implementation as the radiation pattern will change due to the surround components. As such, during selection of antenna, you can select one with high peak gain to compensate for the loss. Molex can offer assistant to choose the best location and best tuning in-order to meet this peak gain requirement.
