Budget: 1500 USD Deadline: 3 days

Hi, I hope you are doing well.
I’m an experienced software developer and can create the software for your banknote exchange machine, handling acceptance of 100 and 200 denomination notes and issuance of 10 and 20 denomination notes. I will implement full control and error handling for the CashCode bill acceptor and Puloon 2000 dispenser, along with a simple user interface, service mode, and statistics tracking.
I have experience working with hardware interfaces and protocols similar to CashCode and Puloon, and I’m comfortable integrating software with real equipment. I work as an individual contractor and can collaborate under a formal agreement or contract as required. I’ll ensure the system is reliable, secure, and user-friendly.

I can start immediately once technical documentation is provided and can deliver a fully functional solution according to your specifications.
Looking forward to discussing the next steps.

Greetings!
The IcornA team is interested in developing software for your banknote exchange project. We have the necessary technical foundation to work with peripheral devices and data transmission protocols, which is critical for the stable operation of CashCode bill acceptors and Puloon 2000 dispensers. Our experience in developing high-load technical infrastructure and process automation allows us to implement a complete device management cycle, including low-level error handling and ensuring the accuracy of financial transactions. We understand the specifics of working with real hardware and are ready to implement reliable change-giving logic, a service mode for cash collection, and a detailed logging system for statistics.

IcornA operates as a cohesive team of technical specialists, so we consider the contract collaboration format as a specialized development company. This guarantees you clear adherence to deadlines, a systematic approach to testing software on real protocols, and further technical support for the product. We are ready to review your detailed technical documentation to assess the stages of implementation and finalize the project architecture.

Good day!
I have experience working with CashCode and Puloon equipment, as well as with similar devices, including setting up communication protocols (CCNET/serial interface), processing status codes, errors, and implementing the logic for accepting and dispensing banknotes. This allows me to confidently design the exchange logic (accepting 100/200 and dispensing 10/20) taking into account all typical situations and failures.

I work as an individual, and if necessary, I can sign an official contract. For a more accurate assessment of timelines and costs, I would like to review your technical documentation on specific models of devices and the requirements for the target platform (OS, technology stack, type of interface). I am ready to discuss the project details in private messages.

Good day.
The task is clear — it is about developing software for a banknote change machine that works with a real bill acceptor and dispenser, including handling hardware errors and a service mode.

I see the architecture of the solution as follows:

a separate module for working with the bill acceptor;

a separate module for working with the dispenser;

controlling logic for the change transaction;

a simple UI for the user + service mode (statistics, tests, logs).

I have no experience with CashCode / Puloon, but I learn quickly!

The format of cooperation is as an individual.
I am ready to familiarize myself with the technical documentation and discuss the details of implementation, stages, and timelines. Expand

Hi,
I’m interested in your project for developing software for a banknote exchange machine.
I have experience working with CashCode and Puloon devices, including device integration, error handling, and protocol management. I can develop software to accept 100 and 200 bills, dispense 10 and 20 bills, with a simple user interface, service mode, and statistics tracking.
I can work as an individual contractor or through a company. I can discuss implementation details, timelines, and costs only after receiving a clear technical specification and work conditions.
Ready to start the project once all requirements are clarified.

Hello! I am ready to complete this project and have extensive experience in developing various applications.

Hello! My name is Vitaly.
The task of developing software for a banknote exchange machine is clear to me: accepting 100/200, dispensing 10/20, correct error handling for the bill acceptor and dispenser, a simple user interface + service mode with statistics.
I have not previously worked directly with similar devices (CashCode/Puloon 2000), but I have practical experience in integrations with external devices via serial interfaces (RS-232/USB-Serial), protocol analysis, working with asynchronous data streams, timeouts/retries, as well as building robust logic with logging and diagnostics. I am ready to quickly learn CCNET for CashCode and the Puloon protocol based on your documentation/on a stand with real equipment.
Collaboration format: I can work as an individual under a contract / through an individual entrepreneur/company - whichever is more convenient for you.
To accurately assess timelines and risks, I would like to clarify a few things:
Terminal platform: Windows or Linux? What hardware (PC/controller)?
Connection of CashCode and Puloon: RS-232 directly or through a USB converter? Are the port parameters known?
Exact models of CashCode and Puloon 2000 and what protocol/mode is planned to be used.
Requirements for the UI (touch/screen, languages) and for the service mode (what statistics, how to export).
Are there any additional requirements for security/audit of operations (event log, reports, remote diagnostics)?
If you send the documentation/technical specifications, I will propose a work plan: quick prototype communication with devices, stand tests, implementation of business logic for exchange and errors, service mode/statistics pilot.
I am ready to discuss the details and start with the prototype in the coming days. Expand
