HSBC announced that it will begin the conversion to contactless technology this month, replacing all customer banking debit cards, according to ThinkMoney.com.

The bank will start to roll out the new contactless cards to existing customers whose debit cards are due to expire this month and then continue the process as cards expire. Customers who don’t want a contactless card can opt out by contacting their bank before their current card expires.

Visa, in partnership with Monitise, has launched a suite of new mobile financial services on its revamped Debit Processing Service platform, enabling mobile phone users to check their account history and balances, transfer funds between accounts, and receive real-time transaction alerts.
