ABSTRACT OF THE DISCLOSURE An input data-collating device comprising an electronic memory device, wherein the electronic memory device is stored with a series of record data supplied from an input key device, each of which is formed of a plurality of words. Collation is made after read out between at least a specified word selected from among a plurality of words included in the respective record data previously written in the elec- tronic memory device and the corresponding specified word included in said plural record data subsequently written in the electronic memory device in order to ascertain whether said specified word has already been correctly written in the electronic memory device. A data certifying the correct entry of initial input is written in the electronic memory device after said correct entry has been provided by colla- tion. When a series of record data finally read out from the electronic memory device is transmitted to the following data-processing device, the certifying data is used to determine whether the initial input data has been correctly written in the memory device.
