+### Card Template Pairs
+
+#### Create a card template pair
+
+Both templates must be published (status: `ready`) and unpaired. Valid protocol
+combinations are both SEOS, or Apple DESFire with Google Smart Tap.
+
+```python
+pair = client.console.create_pass_template_pair(
+    name="Employee Badge Pair",
+    apple_card_template_id="0xapplet3mp14t3",
+    google_card_template_id="0xgoogl3t3mp14t3"
+)
+
+print(f"Created pair: {pair.name} (ID: {pair.id})")
+```
+
+#### List card template pairs
+
+```python
+result = client.console.list_pass_template_pairs(page=1, per_page=50)
+
+for pair in result['card_template_pairs']:
+    print(f"{pair.name} (ID: {pair.id})")
+    if pair.ios_template:
+        print(f"  iOS: {pair.ios_template.id}")
+    if pair.android_template:
+        print(f"  Android: {pair.android_template.id}")
