Bank teller — tasks, one by one

Routine transactions

This is the longest-running automation story on the site: ATMs, then online banking, then mobile apps have each removed a layer of counter transactions over three decades, and branch networks have contracted accordingly in most developed markets. The remaining counter volume is skewed towards customers who cannot or will not use digital channels.

The contraction has been gradual and uneven, and several banks have reversed branch closures after losing customers. Automation of transactions did not eliminate the role; it changed the mix of who comes to the counter and why.

Identity, fraud and compliance checks

Automated transaction monitoring flags patterns, but the intervention that stops an elderly customer withdrawing their savings for a scammer happens at a counter, face to face. Regulators in several markets now expect branches to play this role, which has turned a residual task into a valued one.

Regulators expecting branches to play this role depends on branches existing. Where networks close, the expectation migrates to phone and app channels rather than protecting the counter.

Helping with the complicated cases

These cases are emotional, document-heavy and legally sensitive, and they are the reason customers still travel to a branch. Digital channels handle the median; the branch handles the exceptions, and exceptions are a rising share of what walks in the door.

Exceptions are a rising share of what walks in the door because the routine left, not because there are more exceptions. A branch serving only exceptions serves far fewer people and needs far fewer staff.

Recognising a need and referring

Banks have repositioned the counter towards conversation and referral because that is what a physical presence is worth. Systems prompt the teller with what to offer; whether the conversation happens well depends on the person, and banks measure and pay for it.

Referral targets make the role measurable, which cuts both ways: a counter that does not hit them is easier to close. This task ties the job to a sales number rather than to a service need.

Teaching customers the digital channels

It is a strange task — teaching customers to need you less — but banks have formalised it, sometimes as a distinct role, because it lowers cost and reduces fraud exposure. It is stable for as long as there are customers who have not made the transition, which in ageing populations is a long time.

The task is explicitly about teaching customers to need the branch less. It is stable only for as long as there is a cohort that has not made the transition, and that cohort shrinks every year.
