Kada antenna et nepeg ya independentin na-optimize, saray kompromiso ed sakey et mangapekta ed sananey. Say inkakomplikado na panaggawa et mamaaligwas ed bilang na depekto. Say 40-60% ya premium ed sakey a frequency et mabetbet ya mangiter na kompromiso ed performance ed parehon frequency.

Parad saray bilding ya multi-tenant ya walaan na nanduruman sistema ed nanduruman grado, mas praktikal so nanduruman kredensyal. Aliwan tanton elegante, mas maong so epekto to, tan mas abeba so gastos to legay ilalabas na panaon.

 

Saray detalye na detalye ya importante, base ed saray ag-inkayadyari na deployment ya anengneng mi:

 

 

Parad saray balon deployment ya importante so seguridad: DESFire EV2 ed 13.56MHz. Say EV3 et mangaarum na daiset iran inyaligwas ed premium pricing-mairap ya ikakatunongan ed paway na gobierno odino proteksion na atagey a balor na kaykayarian. Kumpirmaen so encrypted sector authentication, aliwan say CSN- labat. Manbadyet na $2.50-4.00 kada keyfob ed karakel.

 

Parad legacy LF maintenance ya ag nayarin i-upgrade: EM4100 o TK4100 parad napanmatalkan ya compatibility ed sankaabebaan ya gastos. Awaten ya maong so limitasyon na seguridad. Kaukolan moy on-reprogramming? Manbayar na daiset ya premium parad T5577.

 

Parad saray transisyon: multi-technology readers imbes ya dual-frequency keyfobs. Say premium na manbabasa et sakey-minsan; say keyfob premium et ompawil ed kada niiter ya kredensyal.

 

Agmo sobran-ipaliwawa. Inaon mi ray proyekto ya mankekerew na DESFire EV3 ya walay 8KB memory parad gym membership systems-$4+ kada keyfob parad saray kapasidad ya ag da lan balot nausar. Say DESFire EV2 ya walay 2KB ya $2.50 et mangiiter na parehon functionality parad satan ya aplikasyon.

 

Agmo met i-under-specify. Say manunan lolooban na bilding ya walay EM4100 ya kredensyal et sakey a desisyon ed seguridad, balanglan ginagawa o andi. No walay man-clone na keyfob tan makagamor na access, say tepet ya "akin et manguusar itayo na teknolohiya ya ag-importante ya clone?" onsabi.

 

Say pampili na frequency et aliwan komplikado no ibiig mo ray desisyon: say pisika manlapud seguridad manlapud kalidad na panaggawa. Say maslak ya pakawetwet et manlalapud marketing ya manlalaok ed sikara, odino say panagsaliw ya akasentro ed unit cost ya ag-ikonsidera so kabuoan ya gastos ed panagkayarian.

 

Mankikimey ed sakey a desisyon ed pangibaki? Mas labay mi kan tulongan ya mangibaga na duga ed unaan nen say man-debug na ag-inmabobon a sistema diad saginonor.
