Read full description

RFID Tag Finder will help you rapidly locate those hard to find tagged items. It is one of a series of apps designed for ASCII2-compatible, Bluetooth® UHF readers from Technology Solutions (UK) Ltd. Using responsive, audible, signal-strength feedback and a dynamic graphical signal meter RFID Tag Finder allows you to rapidly sweep large areas and hone in on just the asset you are looking for. Alternatively, configure Tag Finder to only detect when the asset is very nearby - allowing rooms full of cages, boxes and racks to be rapidly and efficiently searched.Using the built-in, default configurations or a fully, user-specified operation, Tag Finder can be optimized for your asset environment. RFID Tag Finder can be configured for tags encoded using: ∙ SGTIN-96 ∙ GRAI-96 ∙ ASCII ∙ Hex To make life even easier all the necessary encoding configuration can be achieved by simply scanning an RFID tag in the desired format. The target asset identifier can either be entered manually or be scanned from a barcode. SGTIN-96 encoded assets can be specified using GS1 standard identifiers such as GTIN-8, GTIN-12 (UPC), GTIN-13, GTIN-14 or simply using the Item Reference number. GRAI-96 encoded assets can be targeted using GRAI codes or plain asset types. With Hex or ASCII encoding selected a useful, in-built tag scanning screen generates a list of nearby tags, ranked by signal strength to quickly provide a target identifier when demonstrating or familiarising yourself with the operation of the App. Technology Solutions (UK) Ltd (TSL) specialises in the design, development and manufacture of Radio Frequency Identification Devices (RFID) and other multi-technology mobile device peripherals that are used to track products, assets, data or personnel. RFID devices are typically used in transport logistics, stock inventory control, and collection of personal data and attendance. RFID Tag Finder uses TSL's sophisticated, parameterised, ASCII protocol which provides developers with a powerful set of commands to carry out complex UHF RFID transponder operations in a simple, easy to grasp way. Using these simple pre-configured ASCII commands, any TSL ASCII2-compatible UHF RFID reader can be rapidly integrated into applications resulting in un-paralleled levels of productivity. Please note that to explore the full capabilities of RFID Tag Finder requires the TSL 1128 Bluetooth UHF RFID Reader or other TSL ASCII2-compatible UHF reader.

SerialMagic Keys provides a simple yet powerful way to connect wireless RFID GEN2 UHF, NFC & barcode readers, meters, sensors, scales, and other wireless devices to easily get data into iOS apps. Why not just use Bluetooth HID (keyboard mode) devices? Many Bluetooth devices are not supported on iOS, and when they are apps must be updated to work. For example use BLE and MFi devices like idChamp® RFID & NFC readers like NF4, RS4, RS3, 1862, 1128, Allflex RS420, LPR, GPR+ Livestock & readers and countless other models with ALL iOS apps that take typed input, e.g. FileMaker Go. RFID-NFC and barcode enable web apps and native apps for inventory, cycle counting, asset tracking, book scouting, package tracking, medical apps - all apps can be RFID, NFC, Barcode, Sensor enabled with SerialMagic Keys. Supports more Bluetooth scanner models than any product of its kind. Scanfob®, idChamp®, BlueSnap caBLE(tm) Bluetooth to RS232 (BLE) dongles. Bluetooth CaBLE can iOS enable virtually any RS-232 device to iOS. Scanfob® 3002i 2D barcode scanner, Scanfob® 2006 laser barcode scanner, Koamtac KDC Scanners, Socket CHS Scanners, 8Qi, Honeywell, Symbol, and hundreds more. Also works with Bluetooth UHF GEN2 RFID readers like Scanfob® Ultra-BB2, Scanfob® Qid, idChamp EUB 4-port, EUA 1-port embedded Gen2 UHF RFID readers CipherLab 1862, TSL 1128 and NFC readers like Scanfob® NFC-BB2. Read & write NDEF data using idChamp® NF4 & RS4. Keyboard simulation can post NDEF data to any app that can accept keystrokes. Read HID Corporate 1000 cards, iClass, Seos, PROX, HID Mobile Access BLE credentials, Apple Student ID, and more using idChamp NF4, and RS4 for high security applications. Write UHF GEN2 EPC and user memory tags with Scanfob® Ultra-BB2, idChamp 1862, idChamp 1128, and more. Measure distance with Leica Disto E7100i, E7500i, etc. and post Keyboard simulation post measurements to all apps that accepts keystrokes. Use measurement rounding feature for simplified use e.g. round to nearest fraction of foot, meter, inch. Post PosiTector 6000 probe coating thickness measurements to any iOS app. Note when using app with non-genuine scanner, registration code may be needed.
