• Is a set of functions that provide the processing logic and data required to perform an EMV contact transaction
• EMV Co provides the requirements for the EMV L2 kernel and we submit our kernel as of the current specification
• When submitting an EMV L2 kernel to the labs for approval, ID TECH has to define what criteria that kernel is meant to support, this is a terminal configuration

Products:

• NEO 2.0 products support both the v1.10 (Gen 1) and v1.20 (Gen 2)
• Non-NEO 2 products may support Gen 2. Case by case. Some have hardware limitations that prevent it from supporting Gen 2
