Panon Kaarawi so Nabasa ed Saray RFID Tag?

 

Saray passive tag et mankikimey ed antikey iran distansya. Mas arawi so kimey na saray aktibon tag. Say eksakton bilang et mandedepende ed kagawaan, mabetbet, tan no antoy walad baetan na tag tan say manbabasa.

 

Say ebat et importante natan ta inkuan na Qualcomm nen imbeneg a taon ya iiyan da ray UHF RFID readers ed saray phone chips. Angipawit so Zebra na enterprise phone ya walay built-in reader to nen Enero. In-anunsyo na RAIN Alliance so sakey a proyekton standard na smartphone nen Marso. No ontalona irayan sagpot, saray parehon tag ya uusaren na saray managlako pian nasubaybayan so imbentaryo et nayarin nabasa na siopaman ya walay telepono to.

 

 

Maslak ed saray RFID tag ed tindaan et passive UHF. Anggapoy baterya ra. No say sakey a manbabasa et mangipapawit na radio waves, say tag et makasesep na magenap ya enerhiya pian na-power so chip to tan maka-bounce back na signal ya walay identification number to. Say tag a mismo et ngalngali anggapoy nagagawaan to. Say manbabasa so manggagawa ed kimey.

 

Diad maong a kondisyon, say UHF passive tag et nayarin nabasa ed 10 metros. Say maong ya kondisyon et mankabaliksan na lukas ya dagem, anggapoy metal ya asingger, anggapoy likido, say tag et akasentro ed dugan paraan no ikompara ed reader antenna. Saray bodega ya walay fixed readers tan high-gain antennas et no maminsan et makagamor na 12 o 15 metros. Saray detalye na saray managgaway tag et mabetbet ya mangipapasen ya saray sankaabigan ya setup ya anggapo ed saray totoon bodega.

 

Iyan so parehon tag ed metal ya estante tan onleksab so range. Iyan mo ed sakey a bote na danum tan lalon onleksab. Say metal so mangipapatnag na signal. Onsesegep itan na danum. Say orientation na tag ya mipara ed reader antenna et importante met. Say reader ya walay linear-polarized antenna et kaukolan ya aka-align so tag ed sakey a paraan. Saray circular-polarized antennas et mas mamerdona balet ta walaan na pigaran range.

 

 

Saray tag ya abeban-frequency ed 125 kHz et nabasa ed 10 sentimetro o mas abeba ni. Onloob iratan ed saray access card tan animal tracking chips. Saray high-frequency tags ed 13.56 MHz et onabot na sakey metro. Saray payment card et manguusar ed sayan banda. Say antikey a distansya et sakey a tampok. I-tap mo so card ed terminal. Agmo iyawagayway itan manlapud biek na kuarto.

 

Nanduruma iray aktibon tag. Wala ray baterya ra. Manbrodkas ira. Mankikimey ira ed 30 metros, 50 metros, 100 metros depende ed setup. Wala ray sistema na industriya ya manbabasa na saray aktibon tag ed pigaran lasus a metro. Say baterya et mangarum na gastos tan kabaleg. Diad kaunoran et ompatey itan. Balet parad panumbok ed saray kargamento odino luluganan ed sakey a sular, aliwan magenap so passive range.

 

Say tepet ed telepono et nipaakar ed passive UHF. Say telepono et ag makaloob ed angkakabaleg iran antena ya uusaren na saray manbabasa ed bodega. Lilimitaan na saray totontonen no panon karakel so pakayarin i-broadcast na handheld. Inkalkula nen Thomas Brunner ed Kathrein Solutions ya saray phone-based readers et makaabot na 120 sentimetro no sankaabigan. Mas asingger itan ed pan-tap ed payment card nen say pan-scan na imbentaryo manlapud tindaan.

 

 

Si Katherine Albrecht et pigaran taon ya nanpasakbay nipaakar ed RFID. Walay doctorate to ed Harvard. Sikatoy angigapo na grupo na saray manbabakal ya tatawagen ya CASPIAN nen 1999. Nansulat na libro nen 2005 ya tatawagen ton "spychips" iray RFID tag. Inaon na libro so patent filings na IBM tan BellSouth ya mangidedeskribe na paraan pian nasubaybayan iray totoo panamegley na saray tag ed kawes tan basura ra. Inkuan na saray totoo ed industriya ya sikatoy alablabas. Inkuan ton manplaplano ira na mass surveillance. Agnin balot naresolbe so sangsangan. Saray tag et linmoob ed saray produkto anggan panon.

 

Say tepet nipaakar ed privacy et mandedepende ed distansya. Say tag ya manbabasa na duaran sentimetro et mairap ya i-scan ya sekreto. Mas mainomay so tag ya 10 metros so kaarawi to. Say telepono ya manbabasa na metro et walad baetan. No kasin importante itan et mandedepende ed no antoy karga na tag tan no siopay malabay ed satan.
