Hi,
I am an experienced engineer that specializes in new product development and prototyping. After reading your description, I can design the fingerprint scanner for you that will be able to generate the required electrical signal to unlock a car door. Prior to completing my bid, I would like to clarify the specifications. As I understand the description, you want the fingerprint scanner to be implemented. That infers the following:
1) Fingerprint scanner circuit design (hardware)
2) Software development (control programming, database, etc.)
3) Interface with a vehicle.
My question is whether the interface and testing is a part of the project as its inclusion or omission significantly affects the project requirements. Once I have clarified this point with you I will promptly provide you with an accurate bid and detailed proposal; including task list, timeline and fees.
I look forward to hearing from you and hope to be able to work with you on this product development.
