CH214000 | How to do a compliance check: records: electronic documents and records
From HM Revenue & Customs · Compliance Handbook
The terms 'electronic document' and 'electronic record' are interchangeable.
A document is defined in law as 'anything in which information of any description is recorded'.
This covers both paper documents and those held electronically. It also includes the device on which the electronic data or individual documents are stored, for example:
internal or external hard drives containing backed up information/scans of paper documents
CDs or DVDs
memory sticks or cards
record-keeping apps on smart phones or tablets.
Examples of devices considered to be computers, include:
modern constant memory tills and other Point of Sale (POS) systems
smart phones
tablets
