- 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:
“If we could have any security against moods! If the profoundest prophet could be holden to his words, and the hearer who is ready to sell all and join the crusade, could have any certificate that to-morrow his prophet shall not unsay his testimony!”
—Ralph Waldo Emerson (1803–1882)
“A well-regulated militia being necessary to the security of a free State, the right of the people to keep and bear arms shall not be infringed.”
—Second Amendment, U.S. Constitution (1791)
“It seems to me that our three basic needs, for food and security and love, are so mixed and mingled and entwined that we cannot straightly think of one without the others. So it happens that when I write of hunger, I am really writing about love and the hunger for it, and warmth and the love of it and the hunger for it ... and then the warmth and richness and fine reality of hunger satisfied ... and it is all one.”
—M.F.K. Fisher (b. 1908)
