Capturing patient payment cards securely for equipment rentals
Holding a card on file for rentals, overdue days, and damage is essential — and a serious liability if you store card numbers yourself. Here is the safe way to do it.
Equipment rental almost always requires a card on file. You need it to bill the rental, charge for overdue days, and recover the cost of damage or loss. But the moment your staff write card numbers on a form or type them into a spreadsheet, you have taken on PCI risk that most facilities are not equipped to carry.
The modern approach is tokenization. Instead of storing the card, you save it through a PCI-compliant processor, which returns a token your system can use to charge later. The raw card number never touches your servers.
A secure card-on-file workflow should give you:
- Card capture during patient intake, on the patient’s own device.
- Off-session charging, so you can bill the saved card without the patient present.
- Support for every charge type: rental, overdue, damage, loss, or a manual amount.
- Partial and full refunds, with protection against accidental double charges.
That last point is easy to overlook. A retried request or a double-click should never bill a patient twice — robust systems use idempotency keys to guarantee a charge happens exactly once, no matter how many times the button is pressed.
CareRenta captures cards through a PCI-compliant processor during intake and lets you charge off-session with triple-layer double-charge protection and one-click refunds. Read more about secure payments and billing, or contact us to walk through your billing scenarios.
