- PAN truncation – only printing some of the digits on receipts
- Tokenization – only using some of the digits during communication and storage of the transaction

Famous quotes containing the word security:
“The most disgusting cad in the world is the man who, on grounds of decorum and morality, avoids the game of love. He is one who puts his own ease and security above the most laudable of philanthropies.”
—H.L. (Henry Lewis)
“Thanks to recent trends in the theory of knowledge, history is now better aware of its own worth and unassailability than it formerly was. It is precisely in its inexact character, in the fact that it can never be normative and does not have to be, that its security lies.”
—Johan Huizinga (1872–1945)
“Modern children were considerably less innocent than parents and the larger society supposed, and postmodern children are less competent than their parents and the society as a whole would like to believe. . . . The perception of childhood competence has shifted much of the responsibility for child protection and security from parents and society to children themselves.”
—David Elkind (20th century)
