Seals, presumably we have seen more or less, simply speaking, is a one-time lock. It is divided into many categories: ordinary seals, security seals, bolt seals, plastic buckles, container seals, bullet seals, plastic seals, cable seals, metal seals, padlocks and other verification seals. Seals naturally have a lot of benefits, but there are also many advantages to the QR code seals.
The QR Seals have the advantages of good anti-corrosion performance, heat and cold resistance, firm and easy lock, clear identification number, etc. They are widely used in power supply, water supply, chemical, logistics, postal services, finance, foreign trade, commodity inspection, customs, aviation, railways and other departments. They can be printed with barcodes, QR codes, and serial numbers, which are convenient for management. They are applicable to electricity meters, water meters, postal bags, armor closures, instrumentation, power supply, gas supply, water supply, military, petroleum transportation, chemicals, mining, postal services, customs, railways, finance, containers, foreign trade inspections, transportation and product processing, enterprise product inspection, packaging, energy metering, and prevention of theft and leakage, and other industries.
Willa QR code seal be used instead of a normal seal in the future? This has yet to be considered, because each has its own advantage. Now the popularity and the development trend of the QR code is really difficult to predict.
