YOU KNOW WHAT A "WALLET" IS BUT WHAT IS A "PURSE"?
I have not met many Spanish people that know the meaning of "purse". Considering that in Spanish the word "cartera" covers everything it hardly surprising that people don't search for this word. So, to explain: a wallet is generally used by men whereas a "purse" is used by women to store money (notes and coins) as well as important documentation.
By the way, did you know that it is not a requirement in the UK to carry formal identification or an ID card? In the UK, there has been a debate about the need for ID cards for many years but, in the end, the UK still does not issue ID cards.
Hope that helps!
