RF SYSTEM

Sigma EAS System uses a RF System. RF stands for Radio Frequency. Radio frequencies represent a portion of the electromagnetic spectrum between 10 KHz and 300GHz. The radio frequency spectrum contains many bands, roughly divided into 3 ranges, low range, mid range, and high range. In the mid range, the wavelengths are shorter, giving less penetration but faster data transmission. RF EAS System uses the mid range.

RF System is electronic system. A complete EAS System consists of power supply, two or more sensing screens (antennas), and targets (tags) attached to protected inventory. The basic system consists of a transmitting antenna and receiving antenna. The antennas stand on either side of an entrance, exit, or both, so that people must pass between them. Store personnel attach targets to the items they want to protect. Clerks then remove, detune, or deactivate these targets from purchased items at checkout, or pass them around system. If someone should try to exit through the system with an item protected by a live target, an alarm sound. A store employee can then intercept and verify if the item has been properly purchased.

One power supply can power up to three antennas, one transmitter and two receivers. The transmitting antenna creates a RF field. When the system target enters the field, it responds to the transmitter's signal by resonating and emitting a signal of its own. As the receiver picks up the target's signal, it verifies the signal electronically. If verification is positive, the receiver triggers an alarm.


Deactivator

SIGMA RF-EAS deactivation technology integrates with POS procedures. Regardless of tag orientation, efficient non-contact proximity deactivation helps eliminate false alarms. RF-EAS allows simultaneous integration of price scanning and security tag deactivation for maximum efficiency.

SIGMA deactivation
- Available in pad version (CHASSIS IV), or integrated into many scanner models (CHASSIS V) for one stop scan/deactivation
- Supports high speed cashier service
- Offers the largest deactivation range
- Can be placed on or under counter for space savings and flexibility at POS
- Reduces internal theft and unauthorized deactivation with interlock feature
- Does not damage merchandise, cash/credit cards or smart cards
