This field can be used to identify whether the write to the card was confirmed or not. Optional - not available for an Enhancement Transaction The body of a message consists of a series of sub-groups. Each sub-group contains individual data elements with similar functional characteristics such as the CID Details and the Location Details as listed in Appendix C. 4.6.4 Message Types CID Edge Interfaces currently defines the following six message types that can serve a model for device to backend data exchange: • PiccUse • PiccPurseLoad • PiccPassLoad • PiccInitialize • PiccNegativeList • PiccAutoLoadUnloadList Page 49 as
