It seems counterintuitive. Cash is universally useful. Cash is what employees say they want when you ask them. So why does the research — and the experience of companies using choice-based reward cards — consistently show that gift cards outperform cash for milestone recognition?

The Fungibility Effect

Cash merges with everything else in an account. The moment it arrives, it becomes undifferentiated. It pays for petrol, groceries, rent. The connection between the reward and the company disappears almost immediately.

A reward card doesn't merge. It exists as a separate, distinct thing — tied to a specific balance, specific brands, and specifically to the moment it was given. Employees mentally earmark it for something they want, not something they need.

The Permission Effect

Here's something fascinating that comes through clearly in employee surveys: people use reward cards to buy things they wouldn't buy with their own money. Not because the card is more valuable — but because the card gives them permission.

An employee who would never justify spending NGN 18,000 on a spa day for herself will spend a RewardsCard at The Spa without hesitation. The same employee wouldn't spend an equivalent cash bonus the same way — the psychological constraint around personal spending doesn't apply to a reward card.

That experience — the thing she did with the card that she wouldn't have done otherwise — creates a memory associated with the company. That memory is what retention is built on.

The Memory Effect

Academic research from Cornell and other institutions confirms what HR practitioners observe in practice: experiential rewards create stronger and more lasting memories than equivalent cash. The brain encodes experiences differently than financial transactions.

Ask an employee a month after their work anniversary what they received. If it was a bank transfer, most can't remember the amount. If it was a RewardsCard, most can tell you exactly what they bought.

The Social Proof Effect

Cash bonuses are private. Reward cards become conversations. "I got a RewardsCard from the company and spent it on…" is a story that gets told — to a partner, to a colleague, on a team call. This social sharing amplifies the recognition signal far beyond the original recipient.

When Cash Is Still Right

Cash has its place: core compensation, performance bonuses tied directly to business results, and situations where the employee faces genuine financial hardship. Reward cards aren't a replacement for fair pay — they're a supplement to it, specifically for recognition moments.

The rule of thumb: if it's compensation, pay it as cash. If it's recognition, deliver it as a RewardsCard.
