Note
A CRC is a mathematical algorithm applied to the digital expression of data that provides a level of assurance against loss or alteration of data. Best practice recommends that the algorithm consider all tags and data elements within a dataset. When the receiver applies a CRC algorithm to the dataset, a different CRC value indicates that a tag or data element within the dataset has been changed since the sender generated the original CRC value.
