RFID And NFC lapran na shai hkat ai lam hte matut mahkai lam hpa kun?

NFC gaw contactless card hti ai wa, contactless card hte point{1}}point hpe chip langai sha de hpawng de da nna, rfid gaw laika hti ai wa hte tag langai mi lawm ai. RFID gaw shiga hti ai lam hte tara jeyang ai lam hpe chye na lu ai, NFC hpaji masa gaw shiga shada da matut mahkai ai lam hpe ahkyak shatai ya ai. Layman a ga hku tsun ga nga yang, NFC gaw RFID a evolved version langai rai nna, lahkawng maga gaw shiga ni hpe ni htep ai shara kaw galai shai mai ai. Ya aten na NFC mobile phone gaw RFID module a daw langai mi hpe hpaw ya ai, gawgap da ai{{5}in NFC chip langai mi nga ai, dai hpe RFID passive tag hku nna gumhpraw jaw na matu jai lang mai ai; dai hpe RFID hti ai wa hku nna data galai shai ai hte mahkawng da ai lam ni a matu mung jai lang mai ai, NFC mobile phone ni a lapran matut mahkai na matu mung jai lang mai ai. data matut mahkai lam.

NFC a transmission range gaw RFID hta kaji ai. RFID a transmission range gaw metre law law (sh) meter law law du hkra du lu ai. Raitim, NFC hkap la ai laklai ai signal attenuation hpaji a majaw, NFC gaw RFID hte shingdaw yang, tsan ai shara kadun, bandwidth law ai hte n-gun n law ai a akyu ni nga ai. Features.

Application lam gaw n bung ai. Ya aten hta, NFC gaw, jai lang ai electronic jak ni hte matut mahkai na matu grau nna yaw shada ai rai nna, active RFID gaw, galu kaba ai- hpe chye ginhka ai hta grau kaja ai. RFID hpe galaw shapraw ai lam, htingnut ai lam, hkan tam ai lam, arung arai ni hpe hparan ai lam ni hta grau nna jai lang ai, NFC gaw access control, mung shawa mawdaw lam, mobile gumhpraw jaw ai lam hte kaga lam ni hta grai kaba ai lit nga ai.

1. Bungli galaw ai aten

NFC a bungli galaw ai aten gaw 13.56MHz; RFID a bungli galaw ai frequency hta n-gun n law ai, n-gun grai law ai, ultra high frequency hte kaga ni lawm ai.

2. Bungli galaw ai shara

NFC a bungli galaw ai tsan gang ai lam gaw, theoretical hku nna 0~20cm rai nga ai, raitim, dai arung arai hpe chye na ai lam hta, laksan n-gun shayawm ai hpaji masa hpe jai lang ai majaw, bungli galaw ai tsan gang ai lam gaw 0~10cm sha rai nga ai, dai hku nna, hpaga lam a shimlam hpe grau kaja hkra galaw lu na matu; RFID gaw Frequency n bung ai majaw, shi a bungli galaw ai shara gaw centimeter loi mi kaw nna metre shi daram du hkra rai nga ai.

3. Bungli galaw ai ladat

NFC gaw hti ai-rite mode hte card mode lahkawng yan hpe madi shadaw ya ai; RFID hta gaw, card hti ai wa hte contactless card ni gaw, shanglawt ai hpung lahkawng rai nna, n mai galai ai.

4. Matut mahkai ladat

NFC gaw P2P mode hpe madi shadaw ai, RFID gaw P2P mode hpe n madi shadaw ai.

5. Standard tara masa

NFC a npu e nga ai matut mahkai ladat gaw, RFID a npu e nga ai matut mahkai madang hte htap htuk nga ai, dai gaw, ISO144444/IS15693 madang hte htap htuk ai. NFC hpaji masa gaw, LLCP, NDEF hte RTD zawn re ai, grai hkrak hkra galaw da ai upper layer protocols ni hpe mung tsun dan ai.

6. Application field .

NFC hpaji masa gaw- n-gun kaba ai RFID hte htuk manu ai majaw, application amyu myu nga ai. Raitim, RFID madang law law nga ai, kahkyin gumdin lam gaw grau sawng ai. Hpaji masa gaw laksan bungli ni (sh) laksan ra kadawn ai lam ni nga ai ginra ni hta hkan sa ai hpaji masa ni hpe hkap la ai.
