Which industries use the BNR?

mei bnr team finalBecause of the BNR's modular architecture and robust design, it is used in many industries. mei bnr team final

  • In transportation, the BNR operates indoors and outside in: Automatic fare collection (AFC) and ticket vending machines (TVM) Toll collection solutions Parking revenue management solutions

  • In retail, the BNR is used as a cash recycler for: self check-out systems attended lanes unattended kiosks

  • In cash security or financial services, the BNR is used as: a secure cash deposit and ATM terminal part of a bill payment system small-scale banking teller assist systems

In the gaming, casino, and amusement with prize (AWP) markets, the BNR improves efficiency in bill breaker and redemption terminals.


How does the BNR improve my business?

mei bnr module team final 1The average BNR customer experiences an ROI in less than one year. Contact us to find the ROI of your application. BNR-equipped machines also extend the time between machine interventions and require less float than traditional acceptor/dispenser systems, making it the perfect solution for unattended payment applications.

What is the BNR's capacity?

mei bnr module team final 1The loader holds 250 notes, and each recycler module contains a 30-note recycler and a 60-note recycler. In addition, MEI offers a variety of cashbox sizes. Studies have shown that a 600-note BNR cashbox is equivalent to a 2400-note cashbox in a traditional acceptor/dispenser model. Click here for more information.

What interfaces, APIs and currencies are supported?

bnr software team finalThe BNR communicates to the host machine through a USB connection via XFS messages. MEI provides four API options for BNR integration: Win32, .NET, Linux or Java. Many different country currencies are supported by the BNR. MEI continues to expand these on demand, taking advantage of our Swiss team of banknote experts.

Why does the BNR not support existing MEI protocols?

bnr software team finalNeither EBDS nor DIN 66348 support recycling commands, and there was no obvious way to do so. MEI chose to use an industry-standard protocol with a developed cash-recycling vocabulary.

How can the BNR firmware and noteset be updated?

bnr software team finalMEI offers the BNR FlashTool. This tool enables the user to update the firmware, noteset, and configuration settings. This process can be set up to run remotely.

Does each recycler need to be a different denomination?

mei bnr hardware team finalThe denominations of notes recycled are customisable to the customer's needs. Depending on the application, the best configuration may be to set multiple recyclers to the same denomination.

What are the power supply requirements of the BNR?

bnr software team finalIn general, the BNR requires a 24 V 10 A power supply. See the BNR Specifications on the BNR data sheet.

What is the form factor?

mei bnr hardware team finalContact us to receive information on the BNR and its shipping weight. For more information, see the Understanding the BNR page.

How does the BNR calculate change back to the customer?

bnr software team finalThe BNR can calculate change in one of three configurable ways. The default option, called "Best Change", calculates change in a means that provides the fewest number of bills back to the customer. The second option, called "Optimised Change", calculates which notes to provide to the customer in a way that will extend the time between required interventions. Finally, the host machine can tell the BNR which banknotes to dispense without the use of change algorithms.

How long does it take to integrate the BNR?

mei bnr team finalThe integration process is dependent on the complexity of the application and the amount of control the host machine maintains over the cash recycling process, but on average this is a 3- to 9-month process. MEI provides integration best practices and coding shortcuts to simplify the integration.

How do I access BNR modules or assemble the unit together?

mei bnr team finalAll BNR cash modules are locked into the BNR chassis via the interlock module. To understand how to install the main module onto the chassis and install or remove the cash modules, watch BNR training video on unpacking and assembly. For further information, refer to the BNR user guide.

How do I prepare the loader cassette? Are there banknotes I should not use?

loaderThe loader should be loaded with a stack of up to 250 quality notes that are free from tears, folds and foreign objects. For detailed loader use instructions, please watch the BNR training video on Loader use.

To what do the BNR LEDs refer?

mei bnr hardware team finalThe BNR LEDs are used to communicate codes to the operator. There are a variety of LED color and signal combinations that refer to specific messages about the BNR's functionality. For detailed information on BNR LEDs, refer to the BNR training video that discusses the LED, as well as the LED chart in the BNR user guide.

What happens if the loader cassette is filled with more banknotes than available recycler space?

mei bnr hardware team finalThe BNR has built-in logic that controls when and how many banknotes are moved from the float loader to the recycler(s). A user configuration parameter sets the recycler's "low threshold" limit, or the minimum amount of banknotes stored on the recycler before a reload is required. Any time the low threshold limit is reached, the loader will send notes to the recycler to ensure cash is always available for change. This includes after a BNR reset or after dispensing from the recycler. The loader is designed to store notes until they are needed so the BNR can operate longer.

If I have a banknote jam, how do I find it and how do I clear it?

mei-bnr-repair-centre-final-1The BNR has an easy-to-access banknote path that can provide access to most banknote jams without providing access to the BNR's stores of notes. To learn how to clear jams, watch the BNR training video on jam clearing.

What should I do if I see a drop in the BNR's performance?

bnr software team finalA sudden drop in performance could be caused by dirt, dust, or debris in the BNR. The operator can follow the simple cleaning procedures outlined in the user guide using canned air and alcohol swabs. Refer to the BNR training video on how to properly clean and maintain the product.

How is the BNR serviced?

mei-bnr-repair-centre-final-1The BNR is serviced through an Authorized Service Center (ASC). Its modular design allows replacement of the broken module instead of the whole unit. If you need service that is not covered in the BNR user guide, please call your host machine technical support. To find an ASC, contact us.

How many notes are supported in the memory of the BNR?

bnr software team finalThe BNR has built-in memory to identify up to 60 different banknote "types". It is important to understand that every new release of a currency from the central bank has different security features and is treated as a different type by the BNR. For example, there are currently three types of the $100 bill in circulation based on bank releases from 1991, 1996 and 2010. The BNR can be loaded with mixes of bank notes from multiple countries up to its memory limit.

What happens if the loader cassette is filled with a non-recycled note?

mei bnr module team final 1When the BNR detects that a non-recycled note has been extracted from the loader, the BNR will automatically route the non-recycled note from the loader to the cashbox.

Why did MEI select JXFS as an interface standard?

bnr software team finalJXFS (Java eXtensions for Financial Services) is a standard that specifically addresses banknote recycling. It also has a core kernel that can interface and control a variety of financial service devices.
