The company Lifemac has designed iPadcovers that, when closed, look like a leather-bound copy of the Bible.
Ben Holland, a spokesman for the firm, said that he believed a burglar or thief would be unlikely to take what appeared to be a Bible.
"From the evidence we have got, it seems that the Bible is something safer," he said. "Maybe there is an extra level of respect. A lot of people have been in touch with us looking for information on how they can protect their tablets using the Bible."
