Raspberry Pi RFID Programmer

I'm in need of an expert who can help me program a Raspberry Pi to work with an RFID system. The primary purpose of this RFID system is for access control, so the programming should be tailored to this use.

Key requirements:
- Expertise in RFID systems
- Proficient in programming Raspberry Pi
- Experience with access control systems

The Raspberry Pi needs to be programmed to function as an RFID scanner. This will primarily involve barcode scanning, so the ideal candidate will have experience with this type of functionality.

Skills and experience that would be advantageous:
- Proficient in Python or similar programming languages suitable for Raspberry Pi
- Prior experience programming RFID systems for access control
- Familiarity with barcode scanning technology

Please provide examples of previous work that is similar to this project in your proposal.
