MB2100T or Mini-bank 2100t is the style of installing an ATM machine. Using this style, the machine is installed on the wall. It provides the flexibility of installation. It contains everything any other ATM machine contains like CPU, memory, cash dispenser, etc. This style of ATM is weather friendly and provides ADA(Americans with Disabilities) compliant voice guidance systems. Its best feature is its cash dispenser. It has a locking reject bin and a note cassette that slides out very easily. In case CS12 error is encountered, which is again very less likely with this machine as it has a high range of note cassettes, the cash tray slides out very easily. This feature makes fixing the d0111 error effortlessly.
