## What is RFID Scan Scan Write?

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.

## Frequently asked questions about RFID Scan Scan Write

### What hardware is required to use RFID Scan Scan Write?

RFID Scan Scan Write requires a compatible TSL Bluetooth UHF RFID Reader to function. The app itself is free to download and use with the appropriate hardware.

### How does RFID Scan Scan Write encode RFID tags?

The app can encode tags by scanning GS1 barcode information or by directly inputting Hex/ASCII data. It then writes the new EPC value to the tag using the connected Bluetooth reader.

### Can I secure my RFID tags with this app?

Yes, RFID Scan Scan Write allows you to lock tags and specify passwords. This prevents unauthorized modification of the tag data.

### What types of RFID tags are supported?

The app supports UHF RFID tags that are Multi-vendor Chip-based Serialisation compliant, specifically mentioning Impinj Monza 4, 5, 6, and Monza X tags for generating SGTIN-96 compliant EPCs.

### What is the update frequency for RFID Scan Scan Write?

The app was last updated on March 17, 2020, with the latest version being 3.8. Users can expect updates based on developer release schedules.

### Is RFID Scan Scan Write available on Android?

Based on the provided data, RFID Scan Scan Write is supported on iPhone, iPad, and iPod. Platform availability for Android is not specified.

### What is the user sentiment for RFID Scan Scan Write?

The app has a rating of 2.0 stars from 9 ratings. This suggests that users have mixed to negative experiences with the application.

No, the application does not contain advertisements. It is a free application without any in-app purchases or ad support.

## Version history (last 5 releases)

### 3.8 — 2020-03-17

A slider control has been added to the settings that adjusts the sensitivity of the proximity-based target tag detection when the 'Scan Temporary EPC Barcode' is Off. While we still highly recommend that you physically isolate the tag you are writing too, there are situations where this may not be possible. So, if you regularly see the "Too many tags near the reader" error then lowering the sensitivity might help.

From this version, the default for the 'Scan Temporary EPC Barcode' has been changed to Off - this should not affect users who are upgrading, but new users will have the proximity-based target tag detection enabled by default.

### 3.6.1 — 2019-07-08

When encoding ASCII EPCs, a new option is available - Dual-Input Barcode. This option allows the input data to be entered as two separate barcode scans joined using a configurable, Input Separator string (that can be empty).

### 3.4 — 2019-02-07

We have made a few small enhancements for this release:
  Improved performance when writing to small tags
  Tags with an existing EPC over 256 bits long can now be encoded.
  Increased the robustness of the connection to the Reader.

### 3.2 — 2018-06-27

We have added an optional auto-padding feature to the Hex and ASCII encodings that will add one or more of a user-specified, "pad" character to scanned input data that has an invalid length. This padding can be added either to the left or the right of the scanned input. By default, the auto-padding option is disabled so the App behaves as in previous versions. Use the in-App settings to enable and configure the feature.

### 3.1.1 — 2018-03-21

Fixed issue where spaces in the source data caused the Reader to disconnect.
Minor bug fixes and device image update.
