I don't know if this is really relevant to uk.finance. If it isn't then I'm sorry.
Recently I wrote to Barcalys requesting they change some details on my account. It was a properly written letter with my signiture at the bottom.
A couple of days later I recieved a letter telling me they had "lost my signiture card". Does this mean they no longer have my signtiure on file and if so how do they authenticate cheques? Is there a security risk here?
Many thanks.
