Can Vending Machine Take 5 dollar Bills?

https://vendingproservice.com/do-vending-machine-take-2-5-10-20-dollar-bills/ Most of the vending machine that are still working actually do not accept Bills. These are the Non MDB Type that cannot accept any form of Debit Credit Readers and Bill Acceptors. Actually I have a bunch of very Old Vending machines that are the Non MDB and was able to convert them into MDB type. I converted about 3 very old machines to accept Bill Acceptors because they are situated in very good locations. The only reason to convert very old non mdb vending machines to accept bill acceptors if the total sales every month is approximately around $300 then spending : Used Mdb coin mechanism ( $250 ) + Used Bill Acceptor ( $250 ) + Non Mdb to Mdb Converter ( $150 ) + Your Labor time at least 2 Hours ( to make sure that it works. It will only be worth to convert them if you can see the ROI Return of Investment at least 5 to 6 months, otherwise its better to leave your old vending machines the way it is without any conversion.
