A 24-year-old from Swaffham, who used a vulnerable man's bank cards to buy goods on the internet, will have to pay compensation and complete 100 hours of unpaid work.
Sean Rider, of Carter Close in Swaffham, pleaded guilty to two counts of fraud by false representation at King's Lynn Magistrates Court.
The court heard that Rider fraudulently used the victim's bank cards to purchase goods on the internet between Wednesday, May 25 and Friday, June 30 last year.
The investigating officer, PC Matt Hill, said: 'Rider preyed on a particularly vulnerable victim, gaining entry to his house under the guise of offering assistance.
'He then purchased goods online using his bank cards but entered his home address as the delivery address.'
Rider was also given a restraining order forbidding him to contact the victim or enter his road for the next two years.
