Hom CLONED RFID CHIPS

1. RFID chips tuaj yeem rov ua dua hauv peb txoj hauv kev loj: tsawg zaus (LF), siab zaus (HF), thiab dual chip (uas ua ke LF thiab HF chips). Tag nrho cov chip hom no tau sib xws nrog RFID yuam sij. Txij li thaum nruab nrab-1980s, tsawg zaus (LF) RFID chips tau siv dav. Lawv ua haujlwm hauv cheeb tsam 125Khz zaus. Txawm hais tias qee tus neeg xav tias LF RFID chips muaj qee yam “encryption” los yog kev ruaj ntseg, hauv kev muaj tiag, qhov kev ruaj ntseg yuav tsum tau nyob ze rau barcodes dua li lawv cov kev siv tshuab tam sim no. Nws xa tus lej xov tooj wireless feem ntau. Vim tias LF RFID muaj nqis, yooj yim rau nruab, thiab tswj, nws tseem siv dav hauv kev tsim kho tshiab. Cloning LF cov yawm sij no feem ntau siv ob peb feeb, tab sis yuav tsum paub tias muaj ntau hom ntawv rau LF, qee qhov nyuaj rau clone dua lwm tus. Raws li qhov tshwm sim, tsis yog txhua qhov kev pabcuam duplicate tseem tuaj yeem ua raws li txhua hom LF.
2. Cov thev naus laus zis tshiab tshaj plaws hauv kev tswj hwm kev nkag, siab zaus (HF) RFID chips ua haujlwm hauv lub 13.56 MHz ntau zaus. Lawv tiv thaiv kev sib tw thiab cloning siv cov thev naus laus zis encryption. Cov tuam tsev tau pib siv tus qauv no ntau zaus txawm tias nws raug nqi ntau dua rau kev teeb tsa. HF hom ntawv tag nrho encryption thev naus laus zis tso cai rau cov txheej txheem thev naus laus zis uas tuaj yeem siv qhov twg los ntawm 20 feeb rau 2.5 hnub.
3. Dual-chip RFID yuam sij ua haujlwm nyob rau hauv 13.56MHz thiab 125Khz zaus bands thiab integrate LF thiab HF technology. Tus yuam sij no, uas muab ob lub chips rau hauv ib qho, zoo-nyiam los ntawm cov vaj tse tab tom nrhiav kom muaj kev ruaj ntseg tsis tas hloov lawv cov LF tam sim no. Cov qhov rooj nyob hauv tsev feem ntau yog hloov mus rau HF systems, txawm hais tias cov chaw siv pej xeem (gyms, pas dej da, lwm.) txuas ntxiv ua haujlwm ntawm LF systems.
