Radio-frequency identification (RFID) este un tip de tehnologie care se folose\u0219te de unde electromagnetice pentru a clasifica \u0219i urm\u0103ri taguri (etichete electronice) asociate unor obiecte. \u00cen momentul \u00een care un cititor de carduri RFID<\/a> folose\u0219te un puls de interogare, datele digitale sunt transmise prin intermediul tagului pentru a furniza informa\u021bii privind inventarul. Aceste date sunt apoi transmise \u00eenapoi c\u0103tre cititor. <\/p>\n\n\n\n

Tagurile RFID trimit datele electronice c\u0103tre cititorul de taguri RFID. Tagurile includ un circuit \u0219i o anten\u0103 care transmit aceast\u0103 informa\u021bie. Odat\u0103 ce aceasta este receptat\u0103, interogatorul de date va converti undele radio \u00eentr-o form\u0103 diferit\u0103 de date care poate fi utilizat\u0103 mai u\u0219or.<\/p>\n\n\n\n

De ce furtul de date ale cardului este un pericol real?<\/h3>\n\n\n\n

Numero\u0219i speciali\u0219ti \u00een securitate au ar\u0103tat faptul c\u0103 datele personale pot fi u\u0219or furate de c\u0103tre cineva folosing un cititor de carduri RFID<\/a> aflat \u00een proximitate. Judec\u00e2nd dup\u0103 informa\u021biile de\u021binute \u00een momentul de fa\u021b\u0103, inclusiv numeroasele cazuri detaliate \u00een mediul online, putem ajunge la concluzia c\u0103 acest tip de furt reprezint\u0103 un pericol real.   <\/p>\n\n\n\n

Aceste tipuri de fraud\u0103 sunt cunoscute drept RFID skimming<\/a><\/em>. Portofelele care permit blocarea cardurilor RFID sunt produse tocmai cu scopul de a te proteja de asemenea situa\u021bii. Atunci c\u00e2nd un card este activ, chipul lui poate transmite date care anun\u021b\u0103 o tranzac\u021bie chiar dac\u0103 acesta nu a fost folosit propriu-zis. Card blockerul elimin\u0103 acest pericol \u00een totalitate. <\/p>\n\n\n\n

Aceste sisteme de blocare opresc func\u021bionarea microcipului RFID prin reducerea puterii de citire a datelor din partea cititorului de carduri. \u00cen mod normal un RFID reader<\/a> va transmite un semnal care va fi detectat de c\u0103tre microcipul cardului. \u00cen acela\u0219i timp, acest proces poate fi eliminat prin blocarea sau modificarea semnalului RFID ori prin trimiterea unui semnal diferit care interfereaz\u0103 cu cititorul de carduri. <\/p>\n\n\n\n

\u00cen esen\u021b\u0103, tehnologia de blocare RFID poate fi v\u0103zut\u0103 drept un portofel conceput pentru a evita scenariul \u00een care informa\u021bia \u00eenscris\u0103 pe card este citit\u0103, accidental sau prin rea inten\u021bie. Astfel cardurile aflate \u00een posesie sunt \u00een siguran\u021b\u0103. Desigur, improviza\u021biile sunt posibile, \u00eens\u0103 nu recomandate. Unele sfaturi oferite \u00een mediul online includ lipirea unei folii de aluminiu sau a unei pelicule de banda adeziv\u0103 in jurul cardurilor. \u00cen primul r\u00e2nd, aceast\u0103 metod\u0103 nu prezint\u0103 siguran\u021b\u0103 complet\u0103, iar aspectul vizual nu poate fi nici el ignorat \u00een totalitate. <\/p>\n\n\n\n

Moduri de testare a blockerilor de carduri<\/h3>\n\n\n\n

O alt\u0103 improviza\u021bie sugerat\u0103 de c\u0103tre unele persoane aflate \u00een mediul online este folosirea unei huse de telefon mobil pentru blocarea cardurilor. Cu toate c\u0103 este adev\u0103rat c\u0103 \u0219i telefoanele mobile folosesc radia\u021bie RF, materialul folosit pentru fabricarea unor asemenea huse blocheaz\u0103 doar anumite frecven\u021be \u0219i acestea, cu certitudine, nu sunt dezvoltate \u00een acest scop. <\/p>\n\n\n\n

Cea mai simpl\u0103 metod\u0103 de verificarea a eficacit\u0103\u021bii unui sistem de blocare RFID este prin simpla testare a unui card printr-un punct de plat\u0103 care permite scanarea unui card. Pute\u021bi pur \u0219i simplu cere permisiunea de folosire a unui cititor de carduri. Sistemul de blocare ar trebui s\u0103 previn\u0103 citirea microcipului astfel confirm\u00e2nd faptul c\u0103 sistemul de blocare func\u021bioneaz\u0103 \u00een mod corespunz\u0103tor. <\/p>\n\n\n\n

Ce sunt tagurile RFID?<\/h3>\n\n\n\n

Frecven\u021bele radio sunt utilizate de o serie de produse folosite de c\u0103tre oameni \u00een mod zilnic. Acestea includ obiecte comune precum buletinele, cardurile de plat\u0103, cardurile de acces etc. Identificarea prin frecven\u021b\u0103 radio<\/em> este cunoscut\u0103 \u0219i drept RFID. Acesta este un sistem care utilizeaz\u0103 undele radio pentru a citi \u0219i distribui informa\u021bia stocat\u0103 \u00een aceste etichete (taguri) asociate cu diverse obiecte. <\/p>\n\n\n\n

Aceste taguri ale sistemului de identificare prin frecven\u021b\u0103 radio pot fi citite wireless, de la o distan\u021b\u0103. Mai mult de at\u00e2t, aceste taguri au devenit mai mici \u0219i u\u0219or de produs \u00een ultimii ani, iar utilizarea acestora foarte r\u0103sp\u00e2ndit\u0103. Dezvoltarea acestei tehnologii implic\u0103 o serie de riscuri. <\/p>\n\n\n\n

Obiectele men\u021bionate anterior (carduri de securitate, carduri de pa\u0219aport) con\u021bin toate un microchip care este conectat la o anten\u0103. Ele folosesc diferite tipuri de frecven\u021be radio. Cardurile bancare, spre exemplu, sunt setate la o frecven\u021b\u0103 de 13.56 Mhz. Tagurile produselor, \u00een general, folosesc 125 kHz \u0219i 13.56 Mhz.<\/p>\n\n\n\n

Ini\u021bial sistemele RFID au fost create cu scopul de a func\u021biona de la distan\u021ba de c\u00e2\u021biva centimetri. Cu toate acestea, tehnologia aceasta a continuat s\u0103 evolueze \u0219i a devenit mai ieftin\u0103 de produs. Un cititor de carduri puternic este acum capabil s\u0103 citeasc\u0103 informa\u021bie digital\u0103 de la distan\u021b\u0103 de c\u00e2\u021biva metri. Pe scurt, cardurile contactless nu sunt sigure. Sistemele de blocare RFID adaug\u0103 un element esen\u021bial de securitate. <\/p>\n\n\n\n

Care sunt sistemele active \u0219i pasive de blocare a cardurilor?<\/h3>\n\n\n\n

\u00cen general, sistemul de blocare al cardurilor folosind tehnologie RFID poate fi clasificat drept activ ori pasiv. Sistemele pasive, de exemplu huse, materiale de protejare, pot s\u0103 absoarb\u0103 semnalul RFID despre care am vorbit sau pot s\u0103 \u00eei devieze traiectoria. Pe de alt\u0103 parte, sistemul activ folose\u0219te un microchip care ajut\u0103 prin transmiterea unui semnal care fie interfereaz\u0103, fie face ca chipul s\u0103 nu aib\u0103 destule resurse pentru a putea trimite \u00eenapoi un r\u0103spuns. <\/p>\n\n\n\n

Sistemele pasive pot fi \u00eemp\u0103r\u021bite \u00een dou\u0103 categorii distincte. Sistemele de tip reflective loss<\/em> func\u021bioneaz\u0103 prin dispersarea undelor radio. Pe de cealalt\u0103 parte, sistemele de tip absortion loss, <\/em>reduc puterea semnalului RF care ar este folosit, \u00een mod normal, pentru a face ca chipul RFID s\u0103 fie activ. <\/p>\n\n\n\n

Tehnologia implicat\u0103 \u00een ambele cazuri \u00een ambele cazuri este diferit\u0103. Este, desigur, mult mai u\u0219or de \u00eendeplinit scenariul prin care semnalul cardurilor bancare func\u021bion\u00e2nd la 13.56 mHz este deviat sau absorbit. Blocarea cardurilor care utilizeaz\u0103 125 kHz este mai dificil\u0103 din cauza problemelor legate de proximitate pentru men\u021binerea securit\u0103\u021bii cipului RFID.<\/p>\n\n\n\n
