About

RFID Scan Scan Write

This application allows for the rapid commissioning of UHF RFID tags using a compatible Bluetooth reader. It can encode tags with standard or custom EPCs by scanning barcode information or directly inputting Hex/ASCII data. Tags can also be secured with passwords.

Highlights
  • Rapid UHF RFID tag commissioning
  • Encode tags with custom EPCs
  • Scan barcode information for encoding
  • Lock tags with passwords
  • Support for GS1 SGTIN-96, GRAI-96, GIAI-96
  • Utilizes TSL Bluetooth UHF RFID Reader
Read full description

RFID Scan Scan Write requires a compatible TSL Bluetooth® UHF RFID Reader to explore the full functionality of the App. RFID Scan Scan Write is designed to rapidly commission UHF RFID tags with both industry standard and custom EPCs. The App can take GS1 barcode information and then encode tags with GS1 SGTIN-96, GRAI-96 or GIAI-96 compliant EPCs or use scanned Hex/ASCII data directly to generate custom EPC values. Tags can also be locked and passwords specified so that they are secured against un-authorised modification. For Hex and ASCII custom EPCs: First, scan a barcode containing the new EPC value as Hex or ASCII. Secondly, scan the tag’s temporary EPC barcode or just pull the trigger if not using temporary EPC barcodes - ensure the target tag is the only tag near the reader. The reader automatically writes the new EPC to the tag . Working with UHF RFID tags that support Multi-vendor Chip-based Serialisation (MCS) a user can easily commission serialised tags in a simple two-step process: First scan a GS1 GTIN or UPC barcode. Secondly scan the tag’s temporary EPC barcode or just pull the trigger if not using temporary EPC barcodes. The reader automatically writes to the tag an SGTIN-96 compliant EPC. For generating SGTIN-96 tags requires pre-printed UHF RFID tags that are Multi-vendor Chip-based Serialisation compliant. Currently Impinj Monza 4, 5, 6 and Monza X tags are supported. Technology Solutions (UK) Ltd (TSL) specializes in the design, development and manufacture of handheld, Radio Frequency Identification Devices (RFID). TSL’s RFID Scan Scan Write is one of a series of Apps built around TSL's sophisticated, parameterized, ASCII 2 Protocol that allows sets of pre-configured commands to be executed locally within the Bluetooth® UHF RFID reader. The ASCII 2 protocol provides the developer with a powerful set of parameterised commands to execute complex UHF RFID transponder operations in a simple, easy to grasp way . Using these simple, pre-configured ASCII commands, TSL Bluetooth® UHF RFID readers can be rapidly integrated into applications for unparalleled levels of productivity.

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.
