EAS System / antitheft system

Electronic article surveillance (EAS) is a technological method for preventing shoplifting from retail stores or pilferage of books from libraries. Special tags are fixed to merchandise or books. These tags are removed or deactivated by the clerks when the item is properly bought or checked out. At the exits of the store, a detection system sounds an alarm or otherwise alerts the staff when it senses active tags. For high-value goods that are to be manipulated by the patrons, wired alarm clips may be used instead of tags.

EAS Gate
Promatic PDS3210 Electronic Article Surveillance System is designed and manufactured by a team of highly trained electronic engineers in the field of security engineering. The system uses the Radio Frequency technology to tags all merchandise thus allow the merchant with the ability to prevent unpaid item from leaving the store without notice. The PSD3210 while prevent commodities from being stolen effective at the same time it can help to built relationship between customers and store owner. This system is designed to suits all kinds of retail sites, such as supermarkets, AV stores, clothing stores, bookstores, library, drug stores, game arcade and any establishment that have an open shelf business concept etc. This system can also be used to tags on elderly in homes and children in child care centre. The Securitex/Promatic EAS system was manufactured under the ISO9000 standard and carries the CE certification as well.

The PDS3210 system c/w the following advantages:

- High sensitivity and very low false alarm rate as the system adopted the 2nd generation DSP (Digital Signal Processor) technology.

How does EAS work.

Electronic Article Surveillance system (EAS) is a kind of electronic anti-shoplifting system that can decrease shoplifting when retail enterprise implement open-shelf sale this in-return increase sales and profit. EAS system consists of electronic sensors (transmitter and receiver), deactivator system and label or tag. Electronic sensor that are located at store exit and entrance transmitter (TX) will send a unique RF signal at certain frequencies to a receiver (RX) which creates a "RF surveillance zone" around the store exit/entrance. When a product with an active label or hard tag is moved past a this sensor surveillance area, the sensor will detect this tags and sets off an alarm. Radio Frequency (RF) is the most popular and common technology in today EAS system, it adopts Radio Frequency as Transmit and Receive signal, the detection frequency ranges from 7.x~8.xMHz. The advantage of RF EAS system is cost effective.

Intelligent Digital Identification Technology.

EAS Deactifator
PDS3210 series of digital RF sensor using AD transform technology sampling the simulative signal high-speed, prosecuting computerized signal intelligent identification (CSDM) label under noisy background. It is different from the simple parametric technology that it only identifies the spectrum and the functionary periods of label signal. At the same time, it increase filter and decrease noise circuit in these new technology compared with traditional EAS system. With this new technology implemented in PDS3210 sensors it increase the sensitivity but prevent low and false alarm at the same time.

ACR100 SIM Flash

Combining a smart card reader and mass storage into one, the ACR100 SIMFlash is sought after in different applications worldwide. With its superior plug and play feature (delivered by either CCID or HID compliance) and  various flash memory partitioning options, this USB token enhances security and flexibility in storing or running  different kinds of software/applications.

The ACR100 SIMFlash (HID) is a SIM card reader and a 1-GB flash memory combined into one. Designed both to access SIM cards and to store data or applications, it is ideal for GSM solutions such as GSM management software and VoIP applications, electronic payment systems, e-commerce, home banking, transportation, and computer/network access.

i) Serves as a Plug-In (SIM-Sized) Smart Card Reader:
The ACR100 SIMFlash (HID) Smart Card Reader is a reliable and cost-effective smart card reader for security-related applications. It is a high-speed plug-in USB card reader which, paired with mass storage, enables one to do more than simply backing up and managing SIM card information through the PC. It supports most memory and MCU cards conforming to the T=0 and T=1 protocols, and GSM cards conforming to the GSM 11.11 specification.

ii) Serves as a Mass Storage Device:
Furthermore, the ACR100 SIMFlash (HID) is a mass storage device. Being highly portable – with a dimension of 77 mm x 23 mm x 10 mm – makes it a perfect companion for users on the go. There is no need for additional cable and power supply, since the device is bus-powered. Various options for partitioning the flash drive are also available; CD-ROM, boot disk and public, and locked and hidden areas can all be accessed within the same device.

iii) Plug and Play Feature
Aside from its capabilities for mass storage, the ACR100 SIMFlash (HID) also has a plug-and-play feature made possible by its being compliant with USB HID (Human Interface Device). This eliminates the need for driver installation, allowing for the device’s easy integration into the PC environment.

The differences between the ACR100 SIMFlash (CCID) and the ACR100 SIMFlash (HID)

**What is CCID?

The USB CCID (Chip/Smart Card Interface Devices) specification defines a standard communication protocol for PC/SC smart card readers that connect to a computer via USB, allowing the same host-side driver to communicate with any CCID-compliant smart card reader. This approach to smart card reader communication brings simplified plug and play experience to users.

For Windows Vista, the Microsoft CCID driver is already pre-installed in the Windows package, so there is no need to install any drivers. For Windows XP and 2000, there may be a need for driver installation, depending on your Windows package. However, no explicit user action is needed. You just need to sit and wait for a few moments for Microsoft Windows Update to install the driver automatically upon plugging in your ACR100 SIMFlash to the PC for the first time.

In case Windows Update is not available or when you don’t have Internet connection, please download (or have someone to download) the driver from the ACS website: http://www.acs.com.hk/download.php. Please note that this driver should be used only when the MS CCID driver cannot be installed for some reason.

***What is HID?

From the name itself, a human interface device or HID is a type of computer peripheral that directly communicates with humans, either by taking input from or delivering output to them.

The term “HID” usually refers to the USB HID class, a USB device class that describes HIDs such as computer mice and keyboards. HID support for the ACR100 SIMFlash brings the same plug and play convenience as when you use a mouse or a keyboard that do not require any special driver for most operating systems.

The HID driver is already pre-installed in Windows XP, 2K and Vista that is why there is no need for any driver installation.

AET62 NFC Reader with Fingerprint Sensor

The AET62 NFC Reader with Fingerprint Sensor brings a whole new level of security and flexibility to contactless applications. Combining ACS' ACR122U Near Field Communication (NFC) Reader and UPEK's swipe fingerprint sensor, it provides a secure and convenient platform that simplifies and makes the integration of secure biometric authentication more cost-effective. AET62 facilitates a simple and intuitive exchange of information, making it ideal for applications such as e-Payment, e-Government, e-Healthcare, access control and network security. With its ergonomic design, it enables hassle-free fingerprint and contactless card authentication for users.
The core security mechanisms of AET62 include three-factor authentication and match-on device authentication. Three-factor authentication requires a user to verify something “he has” (smart card), something “he knows” (PIN/password) and something “he is” (fingerprint), before enabling him to proceed with any transaction. Meanwhile, AET62 ensures maximum security by providing match-on device authentication using its default fingerprint algorithm, in which fingerprint template extraction and matching are performed on the device itself and not in the PC, which is more vulnerable to security attacks. AET62 also has an optional secure access module (SAM) for further security enhancement, and can support third party fingerprint algorithms.
Finally, AET62-based systems are more cost-effective than traditional fingerprint systems since they do not require the installation of database, server and network connectivity. Instead, AET62-based systems enjoy the ease of merely matching a live fingerprint against fingerprint templates that are stored and encrypted in the smart card. This allows for complete local-site authentication, in which AET62-based systems only need three components to work: local PC applications (or remote server applications), any contactless smart cards, and the AET62. As a result, developers without an in-depth knowledge of biometrics can integrate fingerprint authentication into smart card-based applications using only AET62’s API and reference documents.
