"E-Ink on my checkbook to remind me to order more cheques!"
A fake label will do just as well in that case. Really? You still use cheques often enough to need to re-order a new book? I vaguely seem to recall writing a cheque 5 or 6 years ago and a few weeks later a new cheque book arrived in the post with a covering letter from my bank telling me that cheques from cheque books over 5 years old may have issues clearing due to fraud prevention measure and to please destroy the old book and use the new one for any further transactions. That means the "new" cheque book is now past its sell-by date and oddly enough, I wrote a cheque the other weeks. I expect I'll get a new book soon and another letter :-)
