Barclays is the only major high street bank in the UK to have deployed Talking ATMs at scale. Over 80% of their 4,100 ATMs now offer the functionality. This includes the 800 ATMs at ASDA superstores which are operated by Barclays. In addition, Northern Bank in the UK have deployed 85 talking cash machines out of their estate of over 200 which amounts to 40 per cent of their estate. Most recent machines installed by banks include a standard audio jack for blind persons to interact with the machine, but these facilities have not yet been enabled.
