HC Deb 21 June 1961 vol 642 cc141-2W
72. Mr. D. Smith

asked the Postmaster-General what progress has been made in the identification of National Insurance stamps as a precaution against their theft from post offices.

Mr. Bevins

Following investigations into the possibilities of marking stamps by perforations and invisible inks, I am pleased to inform the House that, in collaboration with my right hon. Friend, the Minister of Pensions and National Insurance, I have now devised a practical scheme which will enable us to mark National Insurance Stamps in such a way as to help us identify them if they are stolen, even if they have been stuck on National Insurance Cards. This scheme is about to come into operation.
