RFID and NFC a ningmu hte tang shawn ai lam ni

RFID hte NFC hta bung ai lam law law nga ai. Application ni hte frequency band ni hta n-ga, shanhte gaw hpaga lam a madang law law hpe mung garan gachyan ma ai. Daini, grau nna jai lang ai madang masat masa lahkawng hpe ngai tang madun na re.

RFID:

Masha law law gaw IBM ndau shabra ai kaw na RFID hpe chye na ai: supermarket kaw na ramma langai mari ai gaw shi a trench coat hpe jahpring nna, gumhpraw n jaw ra ai sha shi a bill hpe hkap la na matu checkout counter de sa wa ai. Ndai ndau shana ai lam gaw masha ni hpe shani shagu na sak hkrung lam hta RFID hpe jai lang ai lam hpe asan sha madun dan nga ai.

RFID (Radio Frequency Identification) ngu ai gaw, USES radio wave ni hpe matut mahkai na matu, shi hkrai shi chye ginhka ai hpaji masa langai rai nga ai. Madung tara gaw, hti ai bawnu hte laika hti ai lam hku nna, n-gun rawng ai arung arai ni hpe, electromagnetic coupling (sh) inductive coupling hku nna, dai arai hpe matut mahkai da ai tag lapran na data matut mahkai ai lam hku nna, shi hkrai shi chye na lu na matu re. Automatic hpe chye na ai lam gaw, masat da ai arung arai ni hte chye na hkap la ai arung arai ni a lapran na ni htep ai lam hku nna, masat da ai arung arai ni hte seng ai shiga ni hpe shi hkrai shi lu la ai, hte seng ang ai hkan sa ai lam ni a hpang hkan ai ni a hpang hkan ai ni a hpang hkan ai ni a hpang na tara hpe ngut kre hkra galaw na matu, npawt nhpang computer galaw ai ladat hpe shi hkrai shi lu la ai hku nna, masat masa galaw ai jak langai ngai hpe jai lang ai lam hpe tsun mayu ai.

RFID a madung n-gun rawng ai band ni gaw: 125kHz, 134.2khz, 13.56mh, 860{14}}}960mhz, 2.45ghz hte 5.8ghz ni rai nga ai. Bungli galaw ai frequency n bung ai RFID system ni gaw bungli galaw ai tsan ai shara n bung ai hte application field n bung ai. N-gun n law ai band (LF, 125kHz, 134.2khz) RFID system hpe madung hku nna dusat ni hpe chye ginhka lu na matu hte jak rung kaw na jahpan ni hpe lu la na matu jai lang ai. RFID system hpaji masa gaw, n-gun kaba ai (HF, 13.56mhz) gaw grai kungkyang ai rai nna, dai hpe access control, hpaji rawng ai htawt sit ai lam hte kaga lam ni hta grai lang ai. LF hte HF frequency band gaw inductively coupled mode hte bungli galaw ai, madung hku nna bungli galaw ai tsan ai shara kaji ni hte bungli galaw ai. ultra-high frequency band (UHF, 860-960 MHz) RFID system hta electronic tags ni a akyu rawng ai bungli shara gaw 3-6 meters du lu ai, dai gaw logistics, supply chain hte kaga field ni a matu htuk manu ai. Microwave frequency bands (2.45ghz hte 5.8ghz) hpe hka htung ni hpe hparan ai lam hte lam kaba ni hpe shinggyin la ai hta jai lang ai. UHF hte microwave frequency band ni gaw electromagnetic coupling mode hta bungli galaw ai, bungli galaw ai shara gaw grai galu ai.

NFC:

NFC gaw NFC hte seng nna tsun shaga ai hpaji masa hta tsap nga ai. Philips hte SONY kaw nna gyin shalat da ai NFC gaw, n-gun n rawng ai hku chye na lu ai hte matut mahkai ai hpaji masa rai nna, mobile device ni, jai lang ai electronic ni, PCS hte smart control tools ni a lapran na field wireless matut mahkai lam hpe n-gun jaw lu ai. NFC gaw asan sha, hkra ai{2}sensitive hparan ladat hpe jaw ya ai rai nna, dai gaw, jai lang ai ni hpe shiga ni hpe galai shai ya lu ai, shiga ni hte daw jau ai lam ni hpe asan sha, chye na loi ai hku nna lu la mai ai. NFC hpe RFID hpe madung tawn nna gyin shalat da ai, NFC gaw RFID hte grai n shai ai, lamu ga ginra hte ni ai arai lahkawng a lapran na signal transmission hpe madung tawn ai.
