Designed for demanding multi-lane environments, the MX 830 is a robust, consumer-facing payment system that makes quick work of even the most complex payment and value-added transactions. The MX 830 is exceptionally durable and stands up to heavy-use environments. Keys are laser-etched to preserve letters and numbers. The touch screen uses specially hardened glass that resists scratching for a clear view over the life of the device. The non-mechanical stylus has no moving parts or electronics to fail. Plus, field-replaceable modules allow the addition of contactless payment or emerging technologies to preserve investments over time. A smart card reader is factory optional.
