Anatomy ya QR code
Ibimenyetso bitatu bigaragara byerekana QR code decodable kuva impande zose:
| Ikintu | Aho | Uruhare |
|---|---|---|
| Shakisha uburyo | Imirongo itatu nini | Reka scaneri ibone kode nicyerekezo cyayo |
| Uburyo bwo guhuza | Agace gato, hepfo-iburyo | Gukosora lens kugoreka hejuru yuhetamye |
| Uburyo bwigihe | Guhinduranya umurongo hagati yabashakisha | Gushiraho module grid ihuza |
| Agace gatuje | Impera yera impande zose | Gutandukanya kode n'ibidukikije - igice cyibisanzwe, ntugahinge |
| Amakuru & ikosora | Ibindi byose | Umutwaro wo kwishyura, uhujwe no kurengerwa |
Hano hari "verisiyo" 40 - ubunini kuva 21 × 21 kugeza 177 × 177. Impapuro nini zifite amakuru menshi; URL isanzwe igwa hafi ya verisiyo ya 3-5.
Kuki code yangiritse iracyasikana
QR code yashyizwemo Urubingo - Salomo ikosora - imibare imwe irinda CD hamwe nubushakashatsi bwimbitse. Kugeza kumugabane runaka wangiritse, decoder yubaka amakuru yabuze aho kunanirwa. Inzego enye ubushobozi bwubucuruzi bwo guhangana:
- L - gukira ibyangiritse ~ 7%; kode yuzuye.
- M - ~ 15%; burimunsi.
- Q - ~ 25%; byiza kubicapiro bizakemurwa.
- H - ~ 30%; reka ukubite ikirango hagati, urokoke hejuru.
Niyo mpamvu kandi kode yihanganira ikirangantego: mugihe ibyangiritse bigumye munsi yingengo yimari yo kugaruza, umutwaro ukomeza kubaho neza.
Kode ihagaze neza
A gihamye QR code ikubiyemo ibintu byanyuma. Cyakora ubuziraherezo, ntacyo kigura, ntakintu gikurikirana - hindura aho ujya hanyuma usubiremo kode. A. imbaraga kode ikubiyemo URL ngufi yoherejwe na serivisi ya QR: serivisi yandika buri scan kandi irashobora gusubiramo iyo igana nyuma. Handy kubukangurambaga, ariko yongeraho kwishingikiriza (serivise igomba kuguma ari muzima), gukurikirana ubuzima bwite, kandi akenshi abiyandikisha. Iwacu Imashini itanga amashanyarazi itanga kode ihamye gusa - ntakintu kirangira, nta terefone murugo.
Ibyo abantu bashira imbere
- URL - ibyapa, amakarita yubucuruzi, gupakira.
