How to crash an Asda self service till

November 19th, 2007 by Alistair MacDonald Leave a reply »

A night last week I was late light shopping in a local(ish) Asda where I managed to crash the self service till, again.

Late night shopping is something I am doing more and more not having time to go shopping of an evening recently, and although the self service tills are annoying I do use then when there is a queue. The tills at rather annoying because you are supposed to pick up the item, scan it, and then bag it, when in fact I just want to pick up some thing scan them and then put them down. A while ago I managed to find a way round this (that I will not publish here) but it has the problem that I can result in a member of staff needing to enter a pin a few dozen times. Technically this is not a crash, but it is close. I am also pleased to report that the new Tesco tills have a conveyor.

The new bug that I have discovered occurs when you use a “Chip and Signature” card and the shop assistant does not remove the card from the reader before accepting the signature. The till completes the transaction and then gets lost in a loop and needs a hard reboot. The tills run on Windows XP and do not have the start-up sound disabled that I found amusing as it rang out across the store.

For reference my mother was a tester of POS systems (or tills) for a high-street shop chain so I guess this is where I get it from. :-)
