Is the ACR122U Discontinued? What Buyers Need to Know in 2026

Meta description (WordPress SEO field): The ACR122U NFC reader has reached end-of-life. Here’s what that means if you already use one, what to buy instead, and how to avoid counterfeit units.

If you’re shopping for an ACR122U right now, or you manage a fleet of them, here’s the direct answer: yes, the ACR122U has been designated end-of-life by ACS (Advanced Card Systems), its manufacturer. It’s not being manufactured for new stock going forward, and it’s no longer the recommended choice for new deployments. This page explains what that actually means for you, whether you need to do anything about it, and what to buy instead.

What “end-of-life” actually means here

End-of-life doesn’t mean the reader stops working tomorrow. Units already in the field, and any genuine stock still in supplier warehouses, will keep functioning exactly as before — the ACR122U‘s PC/SC and CCID drivers aren’t going anywhere, and existing integrations won’t break on their own. What end-of-life does mean:

• ACS is not producing new ACR122U units indefinitely — once remaining genuine stock in the supply chain is gone, it’s gone.
• Manufacturer support and firmware updates are focused on current-generation readers, not the ACR122U.
• The market has started seeing unofficial and counterfeit units sold under the ACR122U name to fill demand — more on that below.

Do you need to replace your existing ACR122U readers right now?

No — not urgently. If you have a working deployment, there’s no functional reason to rip out ACR122U readers that are doing their job. The practical trigger points for switching are:

• You’re buying more units to expand an existing deployment.
• You’re starting a new project from scratch.
• A reader fails and needs replacing, and genuine ACR122U stock is hard to source.
• Your application needs a card type the ACR122U doesn’t support (see below).

What should you buy instead?

ACS’s actively supported successor is the ACR1552U. It’s built on the same USB, PC/SC and CCID foundation as the ACR122U — so most PC/SC-based software will work with minimal change — but it adds:

• ISO/IEC 15693 vicinity card support, which the ACR122U doesn’t have
• Read/write speeds up to 848 kbps versus the ACR122U’s 424 kbps
• A longer read range — up to 7 cm versus the ACR122U’s 50 mm
• Full manufacturer support and current firmware

If you want the full spec-by-spec breakdown before deciding, we’ve put together a detailed ACR122U vs ACR1552U comparison.

A word of caution: counterfeit ACR122U units

Because the ACR122U is end-of-life, demand for “new” units hasn’t disappeared — and unofficial, non-genuine readers sold under the ACR122U name have shown up in the market to meet it. These can be inconsistent in read range and card compatibility, and since they aren’t genuine ACS hardware, they carry no manufacturer warranty or support if something goes wrong.

If you do need a genuine ACR122U for a specific compatibility reason, or you’re moving to the ACR1552U, buy from a supplier who can stand behind the hardware. BSD InfoTech supplies both the ACR122U and the ACR1552U across India, including bulk and dealer orders.

Quick answers

Is the ACR122U still available to buy? Genuine remaining stock is available through suppliers, but new manufacturing has stopped — treat availability as limited going forward.

Will my existing ACR122U integration stop working? No. End-of-life affects future availability and support, not the operation of units already deployed.

What’s the closest drop-in replacement? The ACR1552U — same core USB/PC/SC/CCID foundation, broader card support, longer range, faster read/write speed.

Can I mix ACR122U and ACR1552U readers in the same deployment? Generally yes, since both speak PC/SC — but re-test any code that specifically depends on ACR122U-only behavior (like FeliCa handling nuances or reader-specific utility tools) before rolling out mixed hardware.
