Rosper provides SUNMI P2 LOA (Letter of Authorization) documentation for all PCI-PTS 6.x certified payment kernels on day 1 of any 2026 US procurement, with the official SUNMI Card Brand LOA bundle covering Visa, Mastercard, Discover, and American Express.
SUNMI P2 LOA package: Key takeaways
- The P2 LOA list is the fastest way through US procurement. If your processor or gateway is already on SUNMI’s LOA list for the P2, deploy time drops from 8-12 weeks to 2-4 weeks because the payment certification work is already done.
- Major US processors are already P2-certified. Rosper stocks the P2 across 8 warehouses across the US and Canada, ships in 2 to 7 business days, and assists with warranty claims under the SUNMI manufacturer warranty. Fiserv, Worldpay, Elavon, TSYS, and several gateways have valid P2 EMV chip + contactless certifications – this guide lists every one we have verified through Rosper’s procurement desk Rosper assists with warranty claims..
- Use Rosper as the SUNMI HQ escalation point. If your processor is not on the LOA list, Rosper can pre-qualify the test environment so SUNMI HQ runs certification in parallel with your procurement rather than serially.
- The LOA is device-and-processor specific. A P2 certified with Fiserv is not automatically certified with Worldpay – always verify the LOA against your exact processor and acquirer before procurement signs.
US merchant card acceptance is moving onto chip and contactless rails at the fastest pace in a decade. Per the Federal Reserve Payments Study, contactless card payments now account for over 30 percent of in-person card transactions at US merchants, and the EMVCo and PCI compliance bar for any new payment terminal entering a US deployment has tightened across every acquirer relationship. For a procurement or compliance team scoping a SUNMI P2 PIN-on-glass terminal for a 2026 rollout, the deployment timeline does not turn on hardware availability. It turns on whether the device-and-processor pair already carries a current Letter of Authorization on file with SUNMI and the acquirer.
The SUNMI P2 family, including the P2, P2 Pro, P2 Mini, and P2 Smartpad, is SUNMI’s PCI PTS 6.X all-in-one Android payment terminal line and one of the highest-volume PIN-on-glass devices in the global merchant fleet. SUNMI ranks among the top three global Android POS hardware brands by IDC shipments, and the P2 series is its core payment terminal platform. Major US acquirers and processors, including Fiserv, Worldpay, Elavon, and TSYS, have already completed EMVCo Level 2 contact and contactless kernel certifications against the P2, which compresses the certification phase of a US deployment from 8 to 12 weeks to 2 to 4 weeks when the LOA package is already in hand.
This SUNMI P2 LOA guide is written for the US or Canadian buyer who has to procure a PCI-certified payment terminal under acquirer or compliance constraints. The audience is a procurement lead at a US retailer or restaurant group standardizing on the P2 across multiple processors, a payments product manager at a North American ISV bundling the P2 into a managed payments stack, a compliance officer mapping the P2 LOA bundle against PCI PTS 6.X and EMVCo Level 2 requirements for an internal audit, or an acquirer or gateway team adding the P2 to a certified hardware list. It is also written for the federal, state, or healthcare procurement buyer who needs the P2 LOA package on letterhead as part of a formal RFP submission.
Rosper Technology is the authorized SUNMI distributor for the United States and Canada and is the procurement and certification escalation point for SUNMI HQ on the P2 family. Rosper stocks the P2, P2 Pro, P2 Mini, and P2 Smartpad across 8 warehouses in North America covering Los Angeles, Ontario CA, Dallas, Atlanta, New Jersey, Chicago, and a Brampton ON warehouse for Canadian customers. Most P2 orders ship from a domestic warehouse within one business day and arrive at the customer site in 2 to 7 business days under the SUNMI manufacturer warranty. For acquirer certifications not yet on the LOA list, Rosper pre-qualifies the test environment so SUNMI HQ runs the new certification in parallel with the buyer’s procurement timeline rather than in series.

If you are working with the SUNMI P2 LOA for a US or Canadian deployment, this guide is written for you. If you are running payment procurement or compliance at a US retailer, a North American ISV, or a multi-store hospitality group, you have seen this line of questioning before.
Rosper provides SUNMI P2 LOA (Letter of Authorization) documentation for all PCI-PTS 6.x certified payment kernels on day 1 of any 2026 US procurement, with the official SUNMI Card Brand LOA bundle covering Visa, Mastercard, Discover, and American Express. “Send me the LOAs for the SUNMI P2.” “Which kernels?” “All of them.” This post is the reference sheet for that conversation. It lists the SUNMI P2 Serial Letter of Authorization package that is available for procurement in the United States and Canada, explains what each LOA covers, and gives you the request path through Rosper.
Rosper is the authorized SUNMI distributor for the US and Canada. We maintain the current SUNMI P2 LOA package for the SUNMI P2 family and deliver it to customers for procurement and certification work. If you need the documents for a specific model (P2, P2 Pro, P2 Mini, or P2 Smartpad), the contact path is at the end.
What a Letter of Authorization is
A Letter of Authorization, or LOA, is a document issued by a card brand or a certification body that confirms a specific hardware and kernel combination has been evaluated against a specific specification and approved for production use. For a US payment deployment, procurement and compliance teams typically ask for LOAs to verify:
- The device is PCI PTS approved.
- The EMV L1 physical layer has been certified for contact and contactless.
- The EMV L2 contact kernel has been certified for each supported card brand.
- The contactless kernel for each supported card brand has been certified.
- The device meets any additional requirements (PCI-PED, Flash, TQM, and similar).
SUNMI P2 LOA documents are the paper trail that acquirers, processors, and compliance auditors look for when they verify that a device model is eligible to process live transactions.
The SUNMI P2 Serial LOA package: what is available
EMV kernels covered in the P2 Serial LOA package
The SUNMI P2 Serial LOA package covers the P2, P2 Pro, P2 Mini, and P2 Smartpad. The EMV kernel on shipping P2-series devices is EMV 100, which is the current SUNMI kernel for this device family.
| LOA document | Coverage |
|---|---|
| EMV L1 Contact | Physical layer for contact (chip) card reads |
| EMV L2 Contact | Logical layer for contact (chip) card processing |
| EMV L1 Contactless | Physical layer for contactless (tap) reads |
| Visa Contactless | Visa PayWave contactless kernel |
| MasterCard Contactless | MasterCard PayPass contactless kernel |
| Amex Contactless | American Express ExpressPay contactless kernel |
| Discover Contactless | Discover DPAS contactless kernel |

The All Documents Package for procurement
These LOAs apply to the SUNMI P2, P2 Pro, P2 Mini, and P2 Smartpad. The complete “All Documents Package” is what procurement teams typically ask for up front.
Which LOAs a US acquirer will ask for
Different acquirers focus on different subsets of the package. For a typical US deployment, the subset that comes up most often is:
- EMV L1 and L2 Contact for chip card processing.
- EMV L1 Contactless plus Visa, MasterCard, Amex, and Discover contactless kernels for tap cards and mobile wallets (Apple Pay, Google Pay, Samsung Pay in the US use the same underlying card-brand kernels).
- PCI-PED for the PIN pad.
UnionPay and JCB contactless coverage
UnionPay and JCB contactless come up if your merchant base includes international travelers or if your processor explicitly supports those brands. They are already included in the SUNMI P2 Serial package, so there is no separate ask.
Canadian deployments and Interac
For a Canadian deployment, the same list applies. Interac is a separate Canadian payment network, and if your Canadian acquirer requires Interac certification, confirm with the acquirer whether that is handled at the device level or at the processor level for your specific integration.
When you need the LOAs in your procurement timeline
In our experience with US and Canadian SUNMI procurements, the LOA request tends to come at two points in the timeline.
Early vendor evaluation request path
The first is early, during vendor evaluation, when a procurement or compliance team wants to confirm that the SUNMI P2 family is eligible for their use case before a purchase order is cut. This is a one-time ask, and Rosper can deliver the package within the same business day.
Acquirer certification request path
The second is later, during acquirer certification, when the acquirer’s certification engineer asks for specific kernel LOAs as part of the device approval review. At this point, the procurement team has already bought the devices, and the ask is process paperwork, not a buy-no-buy decision.
Either way, Rosper maintains the current LOA package and delivers it to customers on request. If the procurement timeline is tight, ask early.
What LOAs do not do
An LOA confirms that a specific hardware and kernel has been certified against a specific specification. It does not:
- Make the device automatically approved by a specific acquirer. Every acquirer has its own certification process on top of the card-brand kernels. LOAs are the prerequisite, not the approval.
- Cover your POS application. The LOAs are for the payment device and its kernels, not your POS app. Your POS app is outside the PCI PTS scope in a semi-integrated deployment.
- Certify your store network. PCI DSS is separate from the device-level LOAs.
- Guarantee future validity. Kernels update, and LOAs are revised when a new kernel version is certified. Always use the current package from Rosper, not a stale copy.
How to request the SUNMI P2 LOA package
Submit your request via the Rosper P2 quote request with the following information:
