Within the next 18 months Transport for London will no longer have Countdown displays at bus stops. Instead they have put bar-codes which passengers can scan with their SmartPhones to obtain bus arrival times. These will be sent by a Premium Rate text message. Another charge for something that was free. Not everyone has a SmartPhone, but TfL does not care. (Information from a Clear Channel technician who was placing a barcode sticker on my local bus stop)

I wanted to clarify your post slightly, and before anyone ask's I do not work for TfL.
The next bus service is currently provided at numerous bus stops (I think around 2000) by a display showing the next 10 or so buses and how many minutes you have to wait for them.
Where this facility is not used/available there are alternatives provided.
A NFC (Near Field Communication) tag or QR (Quick Response) code is provided on a plate attached to the bus shelter or advertising display. Use of
either of these is "free", the user pay's for any data charges from their mobile provider.
A code which you text to a short number is also provided on the bus stop, usually on a metal plate or sticker. Those text's are charged at your standard network rate to send and at 12 p per reply.
