Jak zabr\u00e1n\u00edme odcizen\u00ed bankovn\u00edch a jin\u00fdch karet? Na trhu jsou k dispozici pouzdra na karty RFID proti kr\u00e1de\u017ei a dal\u0161\u00ed produkty, ale pouzdra na karty RFID proti kr\u00e1de\u017ei lze pou\u017e\u00edt pouze pro jednu kartu v sad\u011b.

Co je blokov\u00e1n\u00ed RFID? Radiofrekven\u010dn\u00ed identifikace (RFID) je bezdr\u00e1tov\u00e1 komunika\u010dn\u00ed technologie, kter\u00e1 dok\u00e1\u017ee identifikovat konkr\u00e9tn\u00ed c\u00edle a \u010d\u00edst a zapisovat p\u0159\u00edslu\u0161n\u00e1 data prost\u0159ednictv\u00edm bezdr\u00e1tov\u00fdch sign\u00e1l\u016f, ani\u017e by do\u0161lo k mechanick\u00e9mu nebo optick\u00e9mu kontaktu mezi identifika\u010dn\u00edm syst\u00e9mem a konkr\u00e9tn\u00edmi c\u00edli.

Nap\u0159\u00edklad \u010dip RFID v kreditn\u00ed kart\u011b obsahuje informace pot\u0159ebn\u00e9 pro autorizovan\u00e9 transakce, zat\u00edmco \u010dip RFID v p\u0159\u00edstupov\u00e9 kart\u011b obsahuje k\u00f3d pro otev\u0159en\u00ed dve\u0159\u00ed nebo omezen\u00ed syst\u00e9mu.

Jako dr\u017eitel\u00e9 kreditn\u00edch karet obsahuje karta mnoho na\u0161ich informac\u00ed, a pokud by do\u0161lo k jejich odcizen\u00ed, n\u00e1sledky by byly nep\u0159edstaviteln\u00e9.
