The client requested to implement a Software Block diagram in Arduino Platform. The project consisted in an Interactive RFID Card Reader & Payment Kiosk System with the following characteristics: Use of MFRC522 RFID Module Each card has a different R&W password, generated with an algorithm from the card's UId, the reader needed to implement this algorithm for R&W operations. Verification that the cards were Mifare 1K. Implementation of a Blacklist to avoid access of unwanted cards. Floating-point datatype payment system, each card stores the credit and the system needed to subtract the product value selected by the user. LCD 16x2 display and buttons for user interaction.

Amazing! He's extremely professional and did an outstanding job. He's also very respectful, stays true to his job and sticks to his word. If I could give him a higher rating than 5 stars I would. I was very impressed at the product he delivered and I'm looking forward to working with him again.

Design pcb for cricket scoreboard
Esteban was professional from the start. He interpreted and understood my requirement from the start. He helped me through the process as this was my first project and delivered his to his milestones on time. The design was completed and all the necessary files provided to all me to source a manufacturer and get my project moving. I would be more than happy to use him again should the need arise in the future.
