PCI DSS Requirement 9

A device inventory that holds up under assessment.

PCI DSS requires you to maintain an accurate inventory of every card-reading device, monitor it for tampering, and periodically verify each one is where it should be. A spreadsheet of serial numbers won't survive a QSA's questions. QR-Inventory turns each PED into a self-documenting record — scanned, checked and sealed.

Why it matters

A complete, current device register

Every POS terminal, card reader and PIN-entry device in one authoritative list — model, serial, firmware, location and custodian. Each device carries a unique tamper-evident QR tag, so identifying and verifying one takes a single scan, not a stock-take.

Why it matters

Evidence of monitoring, not just intent

Scheduled check-ins prove devices are inspected on a defined cadence. Every scan, seal-check, move and repair is written to an immutable log — so when an assessor asks "show me", you produce a dated history instead of a promise.

Capabilities

Everything you need for payment-device compliance.

Device inventory management

POS terminals, card readers and PIN-entry devices, each with a unique tamper-evident QR tag for instant identification.

Scheduled check-ins

Weekly or monthly verification reminders confirm each device is present, sealed and operational — on a cadence you set.

Immutable audit trail

Every location, check-in, repair and status change is appended and time-stamped — ready for any PCI DSS assessment.

Device lifecycle tracking

Record when devices are deployed, sent for authorised repair, swapped or decommissioned — a complete chain of custody.

Tamper-evident security

Metalised, tamper-evident QR labels leave clear visual evidence of any attempt to remove or alter the seal.

Compliance reporting

Device inventories, check-in compliance rates and full audit trails, exported in the formats your assessor expects.

Requirements we address

Mapped to PCI DSS Requirement 9.5.1.

PCI DSS v4.0.1 is specific about how point-of-interaction (POI) devices that capture card data via direct physical interaction must be inventoried, inspected and protected. Here's where QR-Inventory does the heavy lifting.

9.5.1
Requirement 9.5.1

Protect POI devices

POI devices that capture payment card data are protected from tampering and unauthorised substitution, with evidence captured whenever a device changes.

9.5.1.1
Requirement 9.5.1.1

Up-to-date device list

Maintain a current inventory of every POI device — make and model, location, and serial number or other unique identifier — kept accurate as devices are added, moved or retired.

9.5.1.2
Requirement 9.5.1.2 / 9.5.1.2.1

Periodic inspections

Surfaces of POI devices are inspected periodically to detect tampering and substitution, at a frequency defined by a targeted risk analysis performed under Requirement 12.3.1.

9.5.1.3
Requirement 9.5.1.3

Staff training

Personnel in POI environments are trained to be aware of attempted tampering or replacement, with clear procedures and an auditable record of device checks.

Requirement references are indicative and provided for guidance. Your PCI DSS scope and validation should be confirmed with your QSA or acquiring bank.

Tamper-evident tags

If a seal is broken, you'll know.

Our metalised QR labels are engineered to fracture on removal, leaving unmistakable visual evidence of tampering. Bound to the device record, each tag turns a routine scan into a documented integrity check.

  • Visible, irreversible evidence of seal removal
  • Each tag uniquely bound to one device record
  • Seal status captured at every check-in scan
  • Alerts raised the moment a tamper is reported
Why QR-Inventory

Compliance that deploys in an afternoon.

Built for teams who need to be audit-ready quickly — and stay that way as they scale.

Instant implementation

Apply the tags, register the devices, start tracking. No heavy rollout required.

Mobile-first check-ins

Staff scan with any phone or tablet — no dedicated hardware to buy or maintain.

Cloud-based platform

Reach your device inventory from anywhere, with continuous backups built in.

Scales 10 to 10,000

From a single store to a national estate — one register, consistent controls.

Expert support

A team that understands PCI DSS and can configure check-ins to your scope.

UK data residency

Compliance data hosted in the UK and processed in line with UK GDPR.

Implementation

Audit-ready in four steps.

STEP 01

Scope

Book a scoping call. We map your device estate and configure your account to your PCI DSS requirements.

STEP 02

Tag & register

Apply tamper-evident QR tags to each device and register its model, serial and location in the system.

STEP 03

Configure check-ins

Set the cadence — weekly or monthly — for staff to scan, verify presence and confirm the seal is intact.

STEP 04

Monitor & report

Track check-in rates, catch exceptions early, and export audit-ready evidence whenever you need it.

Make PCI DSS device tracking a non-event.
