Standalone Card Reader for Stripe Integration

I'm looking for a professional who can help me integrate a standalone card reader with Stripe to accept pre-set amounts of Euros in one-time transactions. The card reader does not need to print receipts - digital receipts will suffice.

Ideal skills and experience:
- Previous experience with standalone hardware integration
- Proficiency in Stripe's API
- Knowledge of card reader hardware and software
- Experience in setting up digital receipt systems
- Strong problem-solving skills and attention to detail

I am open to suggestions for the card reader model/brand. The project needs to be completed within 1 month.
