Tag and Data Set Configuration
Tags are configured in the ViVOpay reader ahead of time so that when a card is selected, a
“data set” (or group) may be instantiated for use in a transaction.
The following illustration shows the basic approach to instantiating the tag database for a
transaction. Global variables (configured through the
Set Configuration
command) are
instantiated when the reader is reset or powered up. When a card is in the field, an AID is
selected and its tags are added to the database. The selection of the AID causes a “data set”
(group) to be selected and its tags are added to the database. As the transaction proceeds,
card tags are added to the database, possibly overwriting or updating some tags that were
previously added to the database.
