Montreal-based SEM inc. is proud to introduce its two small four-price and single-price to MDB conversion kits. Connecting into the changer socket of the machine, those kits will allow you to keep your old 4-price and single-price machines in circulation for many years by adding MDB peripherals such as a bill acceptor. The Plus version of both kits also offers cashless and DEX capabilities. Easy to install and almost configuration-free, both kits allow an additional LCD display showing messages in English, French, Portuguese or Spanish.
