TSB has now added support Android Pay, allowing customers of the bank to pay with their phones.
The moves follows on from Santander, NatWest, Royal Bank of Scotland and Ulster Bank which also added support earlier this month.
Jatin Patel, director of products, TSB, said adding support for Android Pay would help bring even more flexibility to its customers.
"Now that Android Pay is available to TSB customers, it means that they can benefit from this secure and convenient way to make purchases should they so choose.
The roll out leaves Barclays as the last major bank not to take on the resident NFC payment options from the major operating systems.
The company resisted Apple Pay too, continuing to promote its own Bpay service that works with dongles and wrist bands as well as phones.
Other payment systems, including Samsung Pay, are rolling out, but Android and Apple dominate.
Google explained to us at the launch that, although Android Pay is easy for retailers as it requires no extra configuration (unlike Apple Pay), it is harder for the banks because each card in Android Pay gets an alias, meaning that if the transmission is hacked the card numbers won't be the ones on the customer's card and will therefore be useless.
Android Pay launched in the UK in May and includes 'Android Pay Days', promotions once a month offering discounts with different partners each arbitrary 'pay day'.
Contactless payments are already huge business in the UK despite several major retailers, notably Sainsbury's, having yet to support the system even in new build stores.
Transport for London was among the first to accept contactless payments alongside the bespoke Oyster system, and over three million people now regularly use one form of contactless payment to travel, be it phone or debit card.
