加拿大采购需求：我们是条码扫描自动识别、门禁识别、视频监控识别和OEM产品的专家。

I'm reaching out regarding the three units we recently purchased. We're in the process of integrating these devices with our existing access control system and need some assistance. Specifically, I would like to know the proper procedure for programming the QR code in our access control panel. Additionally, we're looking for guidance on how to send this QR code to a mobile device so that individuals can gain access to the site seamlessly. Any detailed instructions or resources you could provide on these topics would be greatly appreciated. Thank you!
