Frequently Asked Questions

Find quick answers to common questions about the product

What protocols do Ci-RD passive readers support?
All Ci-RD passive readers support the EPCglobal UHF Class 1 Gen 2 (ISO 18000-6C) protocol. Most models additionally support the older ISO 18000-6B format for legacy deployments.
Can these readers operate in dense environments?
Yes. Ci-RD models implement dense reader mode and anti-collision algorithms that handle hundreds of tags per second without interference, even when multiple readers are mounted nearby.
Do I need special tags?
No. Ci-RD passive readers work with any standard passive UHF RFID tag compliant with the EPC Gen 2 specification, giving you full freedom to choose tags by cost, size and performance.
