Frequently asked questions

Does this device work with my ERP or HRMS?

What's the pricing for this device?

Pricing is quote-based and depends on the model, quantity and destination country. Email sales@camsbiometrics.com with your site count and country and we reply within one business day. There are no per-transaction fees and no user-count caps.

How long does integration take?

First attendance event flowing to your callback URL in under 12 minutes; full production workflow shipped in under 30 minutes. The API speaks raw JSON over HTTPS — works with PHP, Node.js, Python, Go, Java, Ruby, C#.

Does Cams store biometric data?

No raw biometric data is stored on Cams servers. Templates live on the devices themselves and on your customer's server. Encrypted mathematical representations pass through the Gateway temporarily for synchronization. ISO 9001:2015 certified, GDPR-aligned.
