Two-dimensional code" target="_blank">Kodhi ine mativi maviri inonziwo QR Code, uye zita rizere reQR ndiKurumidza Kupindura.Inzira inofarirwa zvikuru yekukodha panharembozha mumakore achangopfuura.Inokwanisa kuchengeta zvimwe zvakawanda. Iyo ruzivo inogonawo kumiririra mamwe marudzi e data.
Maviri-dimensional bar code/two-dimensional bar code (2-dimensional bar code) inorekodha ruzivo rwechiratidzo chedata ine chaiyo geometric figure yakagoverwa mundege (two-dimensional direction) maererano nemimwe mitemo; Uchishandisa pfungwa dze "0" uye "1" bit hova dzinoumba hwaro hunonzwisisika hwekombuta, uchishandisa akati wandei maumbirwo ejometri anoenderana nebhinari kumiririra zvinyorwa uye ruzivo rwenhamba, kuverenga otomatiki kuburikidza nemidziyo yekuisa mufananidzo kana fotoelectric scanning yekuwana otomatiki kugadzirisa. yeruzivo: ine zvimwe zvakajairika zvebarcode tekinoroji: imwe neimwe kodhi system ine yayo chaiyo yakatarwa seti; chimiro chimwe nechimwe chinotora imwe hupamhi; ine imwe verification function, etc. Panguva imwecheteyo, inewo basa rekuzivikanwa kweotomatiki yeruzivo mumitsara yakasiyana, uye kugadzirisa kwegraphic rotation uye shanduko dzekuchinja.
Features
1. High-density coding, yakakura ruzivo ruzivo: inogona kutakura anosvika 1850 mavara makuru kana 2710 manhamba kana 1108 bytes, kana anopfuura mazana mashanu mabhii echiChinese, ayo akareba kakawanda kupfuura akajairwa bhakodhi ruzivo.
2. Wide coding range: iyo barcode inogona kukodha mapikicha, manzwi, mavara, siginicha, mafingerprints uye rumwe ruzivo rwedigitized, uye kuataura nemabhakodhi; inogona kumiririra mitauro yakawanda; inogona kumiririra data yemifananidzo.
3. Kushivirira kwakasimba kwemhosho uye basa rekugadzirisa kukanganisa: izvi zvinoita kuti bhakodhi yemativi maviri iverengeke zvakanaka kana yakuvadzwa zvishoma nekuda kwekukoromoka, kusvibiswa, nezvimwewo, uye ruzivo runogona kudzoserwa kana nzvimbo yakakuvadzwa yasvika 50%.
4. High decoding kuvimbika: Yakadzika zvakanyanya pane yakajairwa bhakodhi decoding kukanganisa mwero we2/1000000, uye iyo bit kukanganisa mwero haipfuure 1/10000000.
5. Encryption matanho anogona kuunzwa: kuvanzika uye anti-yekunyepedzera zvakanaka.
6. Mutengo wakaderera, nyore kugadzira, uye unogara kwenguva refu.
7. Chimiro, ukuru uye chiyero chebhakodhi zviratidzo zvinogona kuchinjwa.
8. 2D barcodes inogona kuverengwa uchishandisa laser kana CCD vaverengi.
