What you need to know: \tThe new TDR reader is backward compatible with all models that currently support an EMV reader. \tThe only exception to this are C4000 machines, which due to the bezel shape will require continuing use of the KYTronics readers. \tThe TDR readers use a different cable and mounting bracket - you cannot use the KYTronics cables or mounting brackets. \tThere is no need to update software to support the new reader - if your software currently supports the KYT reader - it will also support the TDR reader \tThis new reader has been field tested for over a year before releasing. Every effort has been made to make sure it's trouble-free from the start. What is different about this new reader: Based on feedback and examination of card readers over the last several years, the new reader has been designed specifically to address some common issues: \tThe circuit board is mounted on the top side of the reader to help reduce liquid damage. \tThe card latching arm remains unlocked if there is no power to the ATM. \tThe underside of the reader is open to help drop coins that may be inserted. \tThis new reader does NOT require use of a 'Reset' board when used with older machines.
