Anything that shows proof of passage is valid, so either a receipt with the name of the town or a receipt from a ATM machine. You can at a push even take a selfie which I have done.
Just be sure to number up the receipts though with the circled number in the box on the brevet card with your time and the corresponding number on the receipt. Controllers/Organisers are a good bunch and it makes their lives easier when validating at the end of the ride.
And one last thing, remember to SIGN YOUR NAME on the back of the card.

It's really up to you what you do on the ride, you only need the card if you want to get the ride validated, if you are not interested in that, then you can just breeze through the route and not worry about it... Plenty of club rider groups do this on brevets upto 200km (my observation is that groups of club riders seem to tail off from >200km rides as I think they see them as a bit too long a ride.. )
