QR Codes: The Universal Standard
Best For: Mass marketing, print media and long-range engagement.
-
Pros: 100% free to create (with Belo Marketing QR Code Generator); works on every smartphone with a camera; no hardware required to "broadcast".
-
Cons: Requires the user to open their camera and aim it at the code.
-
Business Verdict: Use QR codes for anything printed - flyers, posters, packaging and window displays. It is your most powerful tool for Customer Acquisition.
NFC (Near Field Communication): The Premium Experience
Best For: High-end retail, repetitive actions and frictionless "taps".
-
Pros: Feels like "magic"; no app or camera required; extremely secure once locked; higher "cool factor".
-
Cons: Requires a small hardware investment (tags/stickers); only works at a range of 4cm or less.
-
Business Verdict: Use NFC for Customer Retention. Place them on "Smart" business cards, restaurant tables for instant ordering or on products for one-tap re-orders.
Bluetooth (Beacons): The Proximity Broadcaster
Best For: Large-scale indoor tracking and push notifications.
-
Pros: Can send messages to phones without the user doing anything; works over a medium range (up to 50m).
-
Cons: Extremely expensive; requires the user to have a specific app installed and Bluetooth turned on; highly intrusive (low privacy).
-
Business Verdict: Generally avoided for small to medium businesses. It is expensive to manage and often ignored by customers who find "pushy" notifications annoying.
