IWriter wants applicants to send a photo of their driver's license?
I would try to check the reputation of the company first. I don't know what IWriter is but if there's a valid reason why they may ask for this, it is possible that it's OK. However, I'd treat it with suspicion and carry out background checks on the company, including with cyber crime authorities. I would not take the request at face value without a lot of checking that it is legitimate. As an example, a company that employs drivers can legitimately require a copy of your driving licence. A company involved with security can require proof of identity and background checks. As I say, I have never heard of this organisation and I have no idea what it does.
