We have two different door lock machines (hardware devices) with their own SDKs and documentation. Each machine can encode data on RFID door cards, but they differ in capabilities, communication protocol, and data format. Machine A (Advanced) Interfaces via COM port (e.g., COM1) Accepts data in hexadecimal format Supports multiple operations: initializer, encoder, dispenser Machine B (Simple) Interfaces via USB Accepts data in ASCII format Only supports encode operation Currently, Machine B encodes cards directly with ASCII data, but we want to replicate the same card encoding process on Machine A so that both machines produce cards that are compatible/identical. Goal Implement an encoding function using Machine A’s SDK so that the encoded cards behave exactly the same as those produced by Machine B. Handle data conversion: ASCII (Machine B) → Hex (Machine A) Ensure the output card works seamlessly with the existing door system. Deliverables A working encoding script/application (Python) that uses Machine A to encode cards exactly like Machine B. Clear documentation on how to run the script, dependencies, and usage examples. Any necessary data conversion utilities (ASCII ↔ HEX). Basic testing procedure to validate encoded cards. Requirements Strong experience with serial communication (COM/USB ports) Familiarity with hex vs ASCII data encoding Ability to work with SDKs and vendor documentation for hardware devices Experience with RFID / MIFARE / hotel lock systems Notes Both machines’ SDKs and documentation will be provided. You will have access to test code we already use with each machine. The task focuses only on the encoding part using Machine A to match Machine B.

Hello, I understand you need to integrate two different door lock machines for card encoding. Machine A communicates via COM and uses hexadecimal data, whereas Machine B uses USB and accepts ASCII. My approach will be to create a Python script that will use the SDK for Machine A to convert ASCII data from Machine B to hexadecimal format so both machines produce identical encoded cards. I will ensure that the output works seamlessly with your existing door system and provide clear documentation on setup and usage. What specific testing methods do you have in mind to validate that the encoded cards are functioning correctly with your current system? Thanks, Shamshad

Hello, I understand you’re looking to integrate two different door lock machines so that Machine A can replicate the exact card encoding results currently produced by Machine B. With extensive experience in serial communication (COM/USB), RFID encoding, and hardware SDK integration, I specialize in creating cross-compatible encoding solutions that bridge protocol and data format differences. My focus will be on implementing an accurate ASCII-to-HEX conversion pipeline so Machine A encodes cards identical to Machine B’s output. For your project, I will develop a Python-based encoding script using Machine A’s SDK, ensuring smooth communication over the COM port and proper handling of hex-formatted data. The script will include utilities for ASCII-to-HEX data translation, error handling for common communication issues, and a simple interface for testing and execution. I will validate functionality by comparing encoded cards across both machines to ensure seamless compatibility with your existing door system. Deliverables will include a tested Python application, well-documented usage instructions, and step-by-step guidelines for validating encoded cards. This will provide you with a reliable, repeatable process to produce fully compatible cards from both devices, minimizing operational disruption while leveraging the more advanced hardware features of Machine A. Thanks, Asif

Hi, I'm BlueLion. I can build this Python script to make your Machine A encode RFID cards exactly like Machine B. The core task is to correctly translate the ASCII data into the specific hexadecimal format required by Machine A's SDK and send it over the COM port. This is a perfect task for me. Since this is an hourly project and I don't have the physical hardware, the most efficient way to work is for you to provide remote access (like TeamViewer or AnyDesk) to a PC with Machine A connected. This will allow me to develop and test the script in real-time. My rate is $15 USD per hour.
