Many of our customers want to know just how secure Bluetooth Low Energy (BLE) — or Bluetooth Smart/Bluetooth 4.0 — communication is. In response, we've made this article to provide basic information about the BLE standard, what it entails and what it means for your security concerns. The BLE Pairing Process How does Bluetooth Low Energy pairing work? Generally, the process of pairing two BLE or Bluetooth Smart devices consists of three phases; the information exchange, key generation and transport-specific key generation. Phase One: Information Exchange The first phase…
RFID Tags RFID tags consist of two primary components; a microchip that processes and stores the information/data and an antenna to receive and transmit RFID radio-wave signals. To read information from the tag/label, a two-way radio-receiver called an interrogator (or reader) sends a radio-wave signal to the tag(s) using its antenna. Tags that are within range of the interrogator's signal will respond with the data stored in its memory. Most RFID tags are passive tags, which use the energy from the interrogator's signal to relay its stored information. Alternatively, battery-…
NOTE: You can sideload an app from any computer and not lose existing data (e.g. does not need to be performed on the computer your iOS device is synced with) 1. Open iTunes 2. Connect iOS device to computer and view inside iTunes by clicking on the name of the iOS device in the upper right-hand corner. 3. Click on the Apps tab. 4. In Windows Explorer, open the folder containing the .ipa file and double-click the file. 5. In iTunes, the app name will appear in the list. 6. Click the “Install” button. It should now say “Will Install” and the app icon should…
This support article demonstrates how to retrieve device information (in this case, we are retrieving information from the idChamp RS3 by using the yACK BLE app for iOS to send the get al command. The yACK BLE application is also available on Android.  1. First, make sure that the device is in BLE mode. The yACK BLE application only works with Bluetooth Low Energy (BLE). 2. Install the yACK BLE application from the App Store. Then, launch yACK BLE. 3. Power on your device. 4. yACK BLE immediately begins searching for nearby devices once…
This article demonstrates how to use the Serial Device Manager to quickly enable multiple card types simultaneously from your Android phone or tablet. 1. Launch iScanBrowser, Cloud-In-Hand Mobile Grid, or SerialMagic Gears. 2. Navigate to the Serial Device Manager (SDM). 3. Power on your RS4 and add it As a connection to the SDM. 4. Once the RS4 is connected, tap on the gear icon (located to the far-right of the Bluetooth name). 5. Tap on RS4 CSN/PACS Credential Type. 6. Select HID 37-bit/40-bit/iClass CSN.
Active Tag: A battery-powered RFID tag that powers the circuitry that transmits the signal to a reader. Active tags differ from passive tags in that they have longer read ranges, a higher price tag, and a larger size (due to the battery). Antenna: The element built into both RFID readers and tags that radiates and receives radio energy. Automatic Identification (also called automatic data capture): The ability to collect and enter data directly into computer systems without human involvement through technologies such as barcodes, biometrics, RFID, and voice recognition. Backscatter: A…
The latest standardization of the Ultra-High Frequency RFID spectrum is the GS1 UHF Gen2 protocol (ISO/IEC 18000-63), which defines the technical specifications (e.g., physical/logical interactions between devices, anti-collision algorithms, security commands, etc.) for RFID devices operating in the frequency of 860–860 MHz. The ITU designated UHF (Ultra-High Frequency) as the radio frequency range of 300 MHz to 3 GHz, while the IEEE defines UHF as only frequencies between 300 MHz and 1 GHz (the rest of the ITU–defined UHF frequency range overlaps with the IEEE's frequency…
Inlay The tag inlay consists of the integrated circuit (IC), an antenna, and a substrate to hold it all together. The inlay, on its own, is a fully functional tag; ready to be packaged into either a smart label or another casing. Integrated Chip (IC) The IC is an electronic circuit or microchip that is manufactured at a semiconductor plant. This microchip contains a memory store and a microprocessor or decision making (logic) unit. The IC is configured either as a passively powered device (powered by inductive coupling generated from another self-powered device) or as an actively powered…
There are a handful of factors that can affect RFID, NFC, or UHF tag read ranges. If you're interested in understanding the various aspects that affect RFID read range to improve your RFID application or use case, continue reading! Tag Characteristics (SOAP) SOAP is an acronym for the various factors that affect an RFID tag's performance; size, orientation, angle, and placement.  Not to be confused with Simple Object Access Protocol (SOAP). S Size O Orientation A Angle P Placement Inlay Size — As a rule of thumb, the bigger…
Decoding the Different Types of RFID There are many different ISO standards, protocols, and physical differences between various RFID tag types.  Choosing compatible readers and tags can be tricky, especially for an RFID novice. For the purposes of this explanation, we’ll only focus on passive RFID, specifically, Low-Frequency (LF), High-Frequency (HF), Near Field Communication (NFC), and NFC Data Exchange Format (NDEF). For a little bit of background, here are some examples of how each type of RFID tag is used. Passive RFID examples: ♦  Employee and / or Student Access control…
