Secure? Of “course” …

Thursday, July 9th, 2009

I tried to enrol online for a course at City Lit a couple of days back. The registration procedure was a little clunky and involved a few inline frames but I managed to battle through it. I was using Firefox and some of the field names did not display in their entirety — so see all of the text you need to highlight them with the mouse and drag horizontally. If you failed to fill in a mandatory field you were dropped back in the middle of the page with no feedback as to what had just happened. Only scrolling to the top of the frame would tell you which fields you had failed to complete.

But, the worst part of the process for me was at the payments stage. When asked to submit my credit card details, I automatically hunt out the sure signs of a secure payment system — basic stuff such as a https in the URL bar and a padlock icon appearing. I saw neither in this case. Ok, it’s possible that the secure part of the site was buried in a frame, so I right-clicked to get a context-sensitive menu on the form hoping that this might reveal some information. It didn’t, so I quickly cancelled my sign-up.

I contacted the City Lit the next day and they assured me that the process is completely secure. This is what they had to say:

Thank you for your observation and be assured we take online card security very seriously. You will be comforted to know that Netbanx collects card payments on our behalf in a secure and PCI compliant environment. PCI DSS (Payment Card Industry Data Security Standard) is a world-wide benchmark mandated by the card schemes for the protection of cardholder identity and transaction information. Netbanx is a reputable company that was founded in 1996 and was the UK’s first payment service provider . We have been using their services since July 2006 without incident … Please be reassured that whilst the padlock does not appear, the payment window within the online enrolment window is secure with 128 bit encryption.

The first part of this sentence doesn’t mean much to me not being a security specialist. However, whilst I’m reassured that they do take security seriously, I’m concerned that the user receives no information or feedback as to the level of site security.

Now, I haven’t got any screen shots to back this up  – and can’t get any without going through the process again — so I’m prepared to admit I may have missed something, although I did examine the page in-depth. Some clear, explanatory text would have set my mind, and presumably others’, at rest — if you take pride in the level of security you offer, then let your users know (maybe skip the bit about PCI DSS though!).

Don’t panic … before reading the instructions

Wednesday, July 8th, 2009

There’s an alarm button positioned on the wall behind the shallow end at my local swimming pool. The button is there, I presume, because there are never any life guards on duty. So, if you’re drowning, please make sure you get out of the pool and press the button to alert someone to the fact.

But, what I like about it the most is the fact that positioned next to it, held on by a fraying piece of sellotape, is a sign on A4 paper that gives you instructions on how to use it: something along the lines of (capitals as per original):

PANIC ALARM BUTTON.

PRESS THE BUTTON ON THE UNDERSIDE OF THE BOX

I love the fact that should you find yourself in a state of panic, you need to carefully read some instructions (which may or may not still be pinned to the wall) to locate the exact whereabouts of the button you need to press to set off the alarm.

Actually, I think all panic buttons should look like Ren and Stimpy’s history eraser button:

Don\'t press the shiny red button!

Don’t make me wait!

I wanted to check out details of the Futurism and Richard Long exhibitions on the Tate website yesterday. On the Tate’s home page there is a rotating clickable “splash” image providing details of various exhibitions and events. Much to my annoyance the details of the Richard Long exhibition were quickly replaced by other information. There was no way to navigate back to it so I had to start exploring the site to find what I wanted. To be fair there is an “exhibitions” link as well as a navigable events calendar, but to locate what you want you need to do a fair amount of scrolling and there’s no obvious way of sorting events.

Tate home page

I would have preferred to have had some way of navigating through the information on the splash image — for instance, some carousel-style controls or something along the lines of the BBC home page:

On the BBC home page, there are clear controls to change the splash image — they even tell you what you’ll expect to see.

The problem with the Tate approach is that each image displays for about five seconds. I counted six images, so that’s thirty seconds you need to wait if you want to take another look at something that caught your eye. One sure way to frustrate your users.
