olemus
kunagine protokollistandard krediitkaardimakseteks avaliku võrgu kaudu (Visa, Mastercard, IBM, Microsoft jt, 1996), põhines X.509-sertifikaatidel, võimaldas müüjal kontrollida krediitkaarti, nägemata seda (teave kaardil läks kontrolliks krediitkaardiasutusele)
= a former protocol standard for credit card payments over a public network (Visa, Mastercard, IBM, Microsoft, etc., 1996), based on X.509 certificates, enabled the merchant to check the credit card without seeing it (the information on the card went to the credit card institution for verification)
