Although EMV technology brings a lot of advantages, one side effect with it is the increasing number of field issues and complications of management of them. The field issue means that there is something unusual during an EMV contact/contactless transaction which may potentially be the reason for a transaction decline or negative user experience. Field issues may be on a wide range, from a simple incorrect message on the terminal screen, a frozen terminal screen, card reading issues, delay in the transaction time, or frequent declines of transactions.
