## Buyer Guidance
- Best for: RFID Access Control — Cards, Fobs & Readers supports RFID and NFC evaluation, comparison, and sourcing decisions.
- Compare first: Compare RFID Access Control — Cards, Fobs & Readers against reader compatibility, chip family, material, and deployment environment.
- What to confirm: Confirm target application, compatibility requirements, customization needs, quantity, and sample expectations before quoting RFID Access Control — Cards, Fobs & Readers.

## FAQ
- Q: Which RFID chip should I use for access control?
  A: For basic access (apartment, small office): EM4100 at 125 kHz is the most cost-effective. For standard security (corporate, campus): MIFARE Classic 1K is the most widely deployed but is cryptographically broken — recommended for replacement during refresh. For high security (government, data center, healthcare): MIFARE DESFire EV3 or HID iCLASS Seos with AES-128 mutual authentication is the 2026 baseline per NIST SP 800-116 Rev 1. We help you choose based on your existing readers and security requirements.
- Q: Can you supply cards compatible with our existing HID or Gallagher system?
  A: Yes. We produce cards and fobs compatible with HID iCLASS, HID SEOS, Gallagher Command Centre, Salto SVN/KS, Keri, Honeywell Pro-Watch, AMAG Symmetry, Lenel S2 NetBox, Software House C·CURE 9000 and Genetec Synergis. Send us a sample credential or tell us your reader model and PACS head-end, and we will match the chip, encoding format and facility-code/cardholder-ID range exactly.
- Q: How secure are RFID access control cards against cloning?
  A: Security varies by chip. EM4100 and HID Prox 26-bit cards have no encryption and can be cloned in seconds with a $30 Proxmark or Flipper Zero — suitable only for low-security perimeters. MIFARE Classic Crypto-1 was academically broken in 2008 — sector keys can be recovered in minutes. MIFARE DESFire EV1 is also deprecated. MIFARE DESFire EV3 and HID iCLASS Seos use AES-128 mutual authentication with Random UID and Originality Signature, with no public crack as of 2026. For any sensitive facility, we recommend migrating to DESFire EV3 or Seos and replacing Wiegand reader-to-panel wiring with OSDP v2.2 Secure Channel.
- Q: What is OSDP v2.2 and do I need it?
  A: OSDP (Open Supervised Device Protocol) v2.2 is the SIA standard (also published as IEC 60839-11-5) for reader-to-panel communication that replaces legacy Wiegand. It runs over RS-485 multi-drop, supports AES-128 Secure Channel encryption, bidirectional messaging, tamper detection, large card formats up to 2048 bits and over-the-wire firmware update. Wiegand is unencrypted and vulnerable to ESPKey-class wire-tap attacks — for any new deployment we recommend OSDP-Verified readers and panels (HID Signo, Mercury LP-series, ISONAS Pure IP, HID VertX V1000).
- Q: Should we switch to mobile credentials and abandon plastic cards?
  A: In 2026, no — mobile is complementary, not replacement. Mobile credential (HID Origo / Salto JustIN / Allegion Mobile / LEGIC Connect / Apple Wallet / Google Wallet) reaches ~10-25% of typical workforce as opt-in for executives, IT, facilities, frequent visitors. Plastic remains primary for industrial / construction (no phone on body in PPE), healthcare patient (sterile + wash protocol), K-12 education (phone policy restrictions), short-term visitor / contractor, and hospitality guest (Apple Wallet hotel keys <2% of stays in 2026). The CSA Aliro 1.0 unified standard (February 2026) will end vendor-cloud lock-in by mid-2027 and may accelerate mobile adoption — but plastic will remain primary through at least 2028.
- Q: Which PACS platform should we pair these credentials with?
  A: Match the credential to your existing PACS or to your security tier. Enterprise multi-site: Genetec Synergis or Lenel S2 OnGuard (now Carrier) or Software House C·CURE 9000 (Tyco / Johnson Controls). Industrial / commercial mid-market: Honeywell Pro-Watch or WIN-PAK. Critical infrastructure / prisons / utilities: Gallagher Command Centre or AMAG Symmetry. SMB cloud: Brivo, Avigilon Alta (formerly Openpath), Kisi, Verkada, Feenics (now Honeywell Pro-Watch Cloud). Federal: FICAM Approved Products List required — Genetec, Lenel, AMAG and Software House C·CURE all maintain APL listings. Tell us your PACS head-end + reader model and we match the chip + encoding format + facility code + cardholder-ID range exactly.
- Q: What is NDAA Section 889 and how does it affect RFID credential procurement?
  A: NDAA Section 889 (effective 13 August 2020 via FAR 52.204-25) bars federal agencies and federal contractors from purchasing or using products containing covered telecommunications equipment from Huawei, ZTE, Hytera, Hikvision and Dahua — including subcomponents. For RFID credential procurement this means: reader OEM must publish NDAA Section 889 attestation (HID, Allegion, Mercury Security, ASSA ABLOY all do); chip silicon supply chain must be auditable (NXP, Infineon, ST, EM Microelectronic all clean); card body lamination + printing must be NDAA-compliant facility. Combine with TAA (Trade Agreements Act) requirement for products made in TAA-designated countries. Proud Tek operates NDAA-compliant manufacturing and provides written 889 + TAA attestation for federal contracts.
- Q: How does the Aliro 1.0 unified mobile credential standard change procurement strategy?
  A: Aliro 1.0 was published by Connectivity Standards Alliance (CSA) in February 2026 with founding members including Apple, Google, Samsung, Aqara, Lockly, HID, ASSA ABLOY, Allegion, dormakaba. Aim: one cryptographic credential format any reader can authenticate without proprietary cloud handshake — ending today's vendor-cloud lock-in pattern (HID Origo vs Salto JustIN vs Allegion Mobile vs LEGIC Connect). 2026 status: standard published, first Aliro-Certified products expected H2 2026; broad reader fleet support 2027-2028. Procurement implication: for greenfield deployments late 2026+, specify Aliro-Certified reader fleet (futureproofs against vendor lock-in); for existing deployments, plan Aliro readiness in next reader-refresh cycle. Plastic credential remains unaffected by Aliro.
