To effectively prevent cheating in the oil sales process, ensure closed-loop management during secondary distribution and gas station sales, strengthen the supervision and control of oil quantity and quality, improve the effectiveness of technical supervision, and reduce human and resource investment in supervision, Honghao Information has independently developed the Smart Seal System Platform, along with smart seal devices and application service platforms. These can monitor the breakage status of seals in real-time, immediately trigger and report alerts upon tampering, and ensure the security of sealed items around the clock. It has broad application prospects in areas such as lock applications, metering supervision, and logistics management.
