Technical Write-Up: Magcard Write Read Utility Program V2017 (Freeware) 1. Overview Software Name: Magcard Write Read Utility Program Version: V2017 License: Freeware Primary Function: Low-level encoding and verification of magnetic stripe cards (ISO 7811 standard). This utility acts as a bridge between a standard PC and a magnetic stripe card reader/writer (typically connected via USB, RS-232, or keyboard wedge emulation). It allows users to read existing track data, write new data to blank cards, and verify the integrity of the encoding. 2. Key Features

Multi-Track Support: Independently read/write Tracks 1, 2, and 3 (ISO format). Character Encoding: Supports 7-bit (Track 1: alphanumeric) and 5-bit (Track 2/3: numeric) encoding. Data Verification: Built-in read-after-write verification to compare source data with encoded data. Bulk/Sequential Encoding: Capability to generate and write incremental card numbers (e.g., for membership IDs). Raw Display: Shows HEX and ASCII representation of the magnetic flux data. Jitter Adjustment: Basic timing calibration for older or non-standard card swipe speeds.

3. User Interface & Workflow Upon launching the executable (no installation required in most free versions), the user is presented with a tabbed or single-pane interface:

Track Selection Panel: Checkboxes for Track 1, Track 2, and Track 3. Data Entry Fields:

Track 1 (79 chars max): %B1234567890^SMITH/JOHN^2503101? Track 2 (40 chars max): ;1234567890=2503101? Track 3 (107 chars max): Custom data.

Control Buttons:

Read: Swipe card → Data populates fields. Write: Position blank card → Click → Encode. Verify: Compares last write buffer with card data.

4. Hardware Compatibility The V2017 version is known to work with common low-cost magnetic encoders, including:

MSR605 / MSR606 series CR80 card printers with encoding modules Generic HID-compliant USB magnetic readers (read-only mode)

Driver Note: On Windows 10/11, you may need to install legacy COM port drivers (Silicon Labs CP210x or FTDI) for writer functionality. 5. Use Cases (Legitimate) | Industry | Application | |----------|-------------| | Hospitality | Encoding hotel key cards (low-security, magstripe only). | | Retail | Creating loyalty/gift cards with unique track data. | | Education | Student ID & library card encoding. | | Testing | QA verifying reader head alignment and swipe speed. | 6. Limitations of the Free V2017 Version

No Encryption: Data is stored and written in plaintext (ISO standard). Not suitable for payment cards (PCI-DSS violation). No Coercivity Detection: Cannot automatically switch between LoCo (300 Oe) and HiCo (4000 Oe). User must manually set if hardware supports it. Legacy UI: No dark mode, limited error logging, fixed window size. Anti-Virus Flags: Some free encoders trigger heuristic warnings due to low-level direct hardware access.
