Ultimate Shopper

Circumvention and Architectures of Control

"...Rob Cockerham’s ‘Ultimate Shopper’ is one of the most famous (and apparently successful) ‘white hat’ attempts to subvert a loyalty card system: Rob replicated the barcode (scanned by the cashier) from his Safeway Club card, and sent out dozens of copies of it to friends and readers of his website, with the aim of creating an ‘interesting’ customer profile on Safeway’s system: one who bought vast quantities of products each month, right across the country:

I want to take the credit for all of my shopping, and for your shopping too! ... Anyone who does this will be lumping their shopping data together with mine. Together we might amass a profile of the single greatest shopper in the history of mankind.

You will still get club card savings, but you will miss out on the odd promotions they have from time to time. Actually, some promotions are awarded at the register, so you may continue to benefit from those, although the rewards will be utterly unpredictable.

Actually cloning the data on the magnetic strip, to create a more foolproof (and less detectable) set of cloned cards, would be another step. Depending on the structure of the supermarket’s loyalty scheme, there may well be thresholds above which the ‘rewards’ for customers increase substantially, and assuming the participants in the cloning scheme can work out a fair or acceptable way to share their rewards, this could mean greater benefits for all of them than actually using their cards individually..."
