MIFARE Classic: Nayarin isulat ed Android, Epektibon Anggapo ed iPhone

 

Nia so compatibility trap ya amatunda ed mas dakel a proyekto na NFC nen say antokaman nin sakey a sengegan. Siopaman ya mantepet no panon ya isulat so NDEF ed MIFARE Classic et mankikimey la sumpad grain na format: Say MIFARE Classic et aliwan sakey a NFC Forum tag type, sakey itan ya ISO/IEC 14443-3A card ya walay proprietary sector tan key structure ya akauna nen say NDEF ecosystem, tan say suporta na NDEF ed satan et wala labat panamegley na sakey a kombension ya wala labat ed tagey na layer.

 

 

Say Android so mangaasikaso ed satan a kombension. say iOS et andi. Say Core NFC na Apple et agbalot akasuporta ed MIFARE Classic, ya saray pamilya na MIFARE ya susuportaan na platform et limitado ed Ultralight, Plus tan DESFire, sakey a posisyon ya paulit-ulit ya akumpirma na saray developer diad saray mismon forum na Apple (Apple Developer Forums). Lapud ag nayarin direktan i-address na iOS so memory na card, ag nayarin isulat na iPhone so NDEF ed satan tan ag nayarin i-display so NDEF ya aka-store ed satan.

 

Say mamapapeligro ed saya legan na evaluation et saray MIFARE Classic tags et ag-onpapatnag ya inatey ed sakey ya iPhone. Say card et walaan na ISO 14443-A UID, kanian maliket ya awaten na Shortcuts app bilang automation trigger, tan say background scanning et nayarin mangilunsad na datin aka-store ya NDEF record na sakey a klase na suportado.

Say anengneng dan kalareker et anggapoy pibabali to ed saray karga na memorya na tag, tan say interon paraan et onkapuy no kaukolan na proyekto so per-unit ya URL ya talagan nabasa na saray iPhone.

 

Say praktikal a totontonen ya onlelereg ed saya: siopaman ya mangikokompara no panon ya iprograma iray NFC tag parad iPhone vs Android et nepeg ya manggawa na acceptance testing ed parehon platform ya walay production chip, agbalot diad Android labat, tan agbalot diad sample na sananey a chip nen say walad purchase order.

 

Mansalita ak na prangka nipaakar ed rekomendasyon, ta say "depende ed uusaren mo" et aliwan mausar ya ebat dia. No saray NFC tags yo et na-tap na totoo, mangiter kayo na antokaman nilikud ed MIFARE Classic.

 

Parad saray grupo ya wala lad loob na Classic-based access system, say desisyon et onkupas ed sakey a variable, tan aliwan saray tag. Saya so nakekeraan ya bilay na panagbasa yo. No saratan a manbabasa et walaan na duara odino taloy taon ya natilak ed sikara tan anggapo lay smartphone ya makasabi ed kredensyal, say pangituloy ed Classic ed sakey a closed loop et sakey a depensan tawag, tan saray praktikal a tepet et magmaliw ya IC sourcing tan UID format imbes ya encoding method, ya saya so pantongtongan tayo ed saray nota tayo edpangi-order na MIFARE 1K tags ed sakey ya aka-install ya sistema. No saray manbabasa so kaukolan ya isalet ed loob na satan a bintana, ag kayo manggastos na kuarta ed sakey a transitional credential. Iyalis so interon kayarian ed AES-based parte diad sakey a kundang tan alaen so gastos a maminsan.

 

Walay komaduan patit ed parehon pamilya, ya masilib ya makaliktar ed interon QA cycles. Say pangiyarum na Smart Poster wrapper ed sakey a rekord, ya iyoopresi na saray kaslakan ya kagawaan ed panag-encode bilang makaaron paraan pian ni-attach so titulo ed sakey ya URL, et manguman ed klase na rekord. Saray rekord ya akabalot ed ontan et ag naala na iOS background scanning, antokaman so walad loob. Say Android testing et onlabas ed amin ya device, anggapoy nagagawaan na iPhone, tan anggapoy error message ed anggan iner ya nayarin diagnose.

 

Ultralight, DESFire tan NTAG 424 DNA: No iner so panagprograma so nagmaliw ya manunan panangasikaso

 

Say MIFARE Ultralight EV1 et asingger ed NTAG21x ed ugali to tan pareho so pangiprograma mo na NFC tags ed satan, ya mas melag so memory budget ton 48 o 128 bytes tan parehon klase na password gate. Anggapoy balon nagagawa.

 

Say DESFire tan NTAG 424 DNA et nanduruman disiplina. Diad sarayan Type 4 ya parte et ag ka mansusulat na bytes ed sakey a flat memory map, man-ooperate ka ed sakey a file system ya walaan na per-file access rights, tan kada makabaliksan ya operasyon et mankaukolan na authentication panamegley na AES-128 key nin unona. Say NTAG 424 DNA et walaan na limaran AES keys ya indetermina na kustomer, manguusar na 3-pass mutual authentication parad protektadon data file, tan walaan na Common Criteria EAL4 certification ed parehon hardware tan software.
