The Problem

Cash is essential.
Handling it is broken.

Retailers can’t go cashless — but the true cost of cash handling is enormous and entirely avoidable.

⏱️

Hours Lost Daily

Staff count tills at start of shift, mid-shift replenishments, end-of-shift balancing, and back-office banking preparation.

3–5 hrs Lost per store per day
🔓

Shrinkage & Theft

Cashier errors, internal theft, external robbery, counterfeit acceptance. Every cash interaction is a risk point.

$9.4B Annual retail shrinkage AU
📊

Reconciliation Errors

Till variances, banking discrepancies, and denomination errors require daily investigation and reporting overhead.

Zero Variances with CIDCO
🪙

Physical Change

Coin orders, denomination management, change-giving errors. Every retail transaction risks human error at the moment of change.

100% Eliminated at POS
How It Works

One transaction.
Zero physical change.

The same EFTPOS terminal already in every store does all the work — no new hardware required.

1

Consumer inserts cash

Cash is inserted directly into the secure cash-handling device. Staff never touch it.

2

Device validates & counts

The device authenticates, counts, and communicates the validated amount to the POS terminal instantly.

3

POS calculates excess

The system calculates any difference between the cash tendered and the purchase price.

4

Consumer taps their card

The consumer presents their debit or credit card at the EFTPOS terminal — just like a normal tap.

5

e-Change credited instantly

The electronic change is credited directly to the consumer’s card. No coins. No receipts to redeem.

6

Merchant settled in real time

Both the merchant credit and the consumer e-change are processed as one unified EFT transaction.

Retailer Benefits

Everything eliminated.
Nothing lost.

Retailers keep every cash-paying customer. They lose every cost and risk that came with them.

🚫

No Till Floats

Eliminate the daily float setup, replenishment, and end-of-shift balancing. The cash drawer is gone entirely.

Real-Time Settlement

Every cash transaction settles electronically in real time. Next-day value into the merchant account — even for cash.

🛡️

Zero Staff Cash Handling

Staff never touch cash. Shrinkage, internal theft, and robbery risk are eliminated at the point of contact.

📈

Faster Checkout

No counting coins, no giving change. Every transaction completes faster — reducing queues and improving throughput.

🔄

Automatic Reconciliation

Cash is validated, counted, and reconciled with the POS and EFT system automatically. No variance reports needed.

🌏

No Hardware Modification

Uses the existing EFTPOS terminal already in every store. No new network infrastructure required. Deploy today.

Use Cases

  • Reduce CIT collection frequency — significant cost saving
  • Staff redeployed from cash counting to customer service
  • Counterfeit and foreign currency risk eliminated

Banks & Acquirers

CIDCO uses existing EFT infrastructure — making it a natural licensing opportunity for banks and acquiring institutions seeking to reduce the cost of cash without excluding consumers.

  • Reduce branch cash processing volumes
  • Generate per-transaction revenue from cash payments
  • CBDC-ready architecture — future-proofed ledger abstraction
  • Financial inclusion narrative for regulatory compliance
  • No MSB or stored-value licensing exposure

Gaming & Venues

Gaming venues already use ticket-based cash redemption. CIDCO extends this model to retail — enabling the same consumer experience with direct card credit rather than physical redemption.

  • Cross-venue digital entitlement redemption network
  • QR-based fallback for card-less consumers
  • Redemption interchange fee opportunity
  • Patented architecture prevents independent build
  • Staff safety improvement — no cash handling

  • Supports unbanked and regional communities
  • Aligns with RBA financial inclusion mandates
  • Australia Post branch network as redemption infrastructure
  • Disaster relief and welfare disbursement capability
  • Eligible for R&D Tax Incentive funding
