Just got my nan a new laptop as she wants to be able to go online and her current laptop is really old. The only thing were worried about is her using her credit cards online. She is 86 and has a problem with giving out her card details over the phone and buying a lot of stuff that my mum then has to return as she doesnt want or remember buying. Were a bit concerned she will hit the bingo sites and not realise how much shes spent (her phone bill is about £200 a month and thats from entering competitions). Is there any software I can install that will restrict the use of credit/debit cards on the laptop?
