Secondly, if you go to collect money, but you don't see the contents of the document clearly, the document you sign should be the company's payroll or salary payment record, or it may be a payment slip for financial bookkeeping. If you collect money and settle accounts with financial personnel, there will generally be no problem;
Thirdly, suppose the content of the document you signed is unfavorable to you, and the relevant documents have preliminary probative force after you sign it. If you sign part of the content without reading it carefully, it will constitute your confirmation of the content, and the relevant personnel can claim rights or raise defenses according to the documents;
However, since you signed the document, there is nothing that attracts your attention, at least it shows that the document belongs to normal materials and there should be nothing particularly unfavorable to you (otherwise, ordinary people will not sign it easily);
Thirdly, from a legal point of view, even if the document you signed contains contents that are particularly unfavorable to you, you can defend it without other evidence. At the same time, the relevant content is invalid if it violates the prohibitive provisions of the law. For example, you can claim that the disclaimer that is not clearly stated is invalid or inconsistent with the facts (because you have not made it clear, you can't judge it positively);
Finally, a piece of paper similar to a receipt should preliminarily judge the fact of collection. In addition, you may leave your job after receiving your salary, and both parties have no other rights and obligations, which will not have much impact on your personal rights.
To sum up, you really don't have to worry or worry. You can ask for one.
As for the signature without fingerprints, it does not affect the legal effect of the document. If a natural person expresses his will, the signature shall prevail.
