Isikhokelo seekhowudi ze-QR

Ikhowudi ye-QR yigridi yolwazi. Ikhamera yakho ifumana iikona zayo, ifunde ipateni, kwaye iphinda iqulunqe umxholo-nangona enye idatha yonakalisiwe.

Isithuba yinxalenye yekhowudi.

Gcina umda omhlophe ocacileyo malunga ne-QR yakho. QR puli igcina ubuncinane iimodyuli ezine zesithuba esithe cwaka, ngoko ke iskena sinokuyahlula kwindawo eyingqongileyo.

Ubumnyama ekukhanyeni uyaphumelela.

Sebenzisa umahluko oqinileyo phakathi kwepateni yakho nemvelaphi. Sifuna i-conservative 4.5:1 ireyishini yokuthelekisa ukuthumela ngaphandle; olu luyilo lwethu lokulinda, hayi umgangatho we-QR.

Vavanya eyona nto iyiyo.

Sikhetha uyilo olunikezelweyo phambi kokukhuphela. Iphepha, ilitha, umgama, kunye nomgangatho wekhamera isebalulekile. Qala malunga ne-30 mm ububanzi kwaye uvavanye ubungakanani bokwenene kunye nomgama.

Ikhowudi yakho yeyakho.

Akukho mhla wokuphelelwa okanye umda wokuskena ofakwe kwikhowudi. Gcina amaphepha neefayile eziqhagamshelweyo zifumaneka. Yenza ikhowudi ye-QR entsha xa utshintsha ikhonkco okanye iinkcukacha ezikuyo.

Ilogo encinci. Uluvo oluhlala luhleli.

Sisebenzisa ukulungiswa kweempazamo eziphezulu kunye nendawo yelogo ethintelweyo. Ukulungiswa kwempazamo kukhusela idatha, kodwa akukho mvume yokufihla i-30% yomfanekiso. Lonke uyilo oluhleliweyo luyajongwa kwakhona.

Sebenzisa umhleli ngendlela yakho.

Sebenzisa ikhonkco lokutsiba ukufikelela kumhleli, i Tab ukuya kulawulo, kunye nezitshixo zotolo phakathi kokhetho oludityanisiweyo. Cofa u-Escape ukuvala ingxoxo. Umbala ngamnye unendawo yokubhaliweyo yokufaka ixabiso le-hex. Iinketho ezikhethiweyo ziphawuliwe kwaye zinemeko ekhethiweyo efikelelekayo. Umboniso uhlaziywa ngokuzenzekelayo, kwaye oopopayi bahlonipha useto oluncitshisiweyo lwentshukumo yesixhobo sakho.

Ukujongwa ngakumbi kwiikhowudi zeQR

I-QR ithetha ukuPhendula ngokuKhawuleza

I-QR imele ukuPhendula ngokuKhawuleza: ukufunda ngokukhawuleza kwakuyinjongo ephambili yoyilo.

Iikhowudi ze-QR nee-CD zomculo

Iikhowudi ze-QR zisebenzisa indlela ye-Reed–Solomon yokulungisa iimpazamo ukunceda ukubuyisa idatha eyonakeleyo. Le ndlela ikwasetyenziswa kwii-CD zomculo.
