<table class='table-style' cellpadding='0' cellspacing='0'>
#foreach ($data as $key=>$contents)
<tr>
<td>{{$contents->card_number}}</td>

Trying to get property of non-object
POST UPDATED:
class UserAccountNumber extends Model
{
protected $table = 'user_account_numbers';
protected $guarded = ['id'];
public function user()
{
return $this->belongsTo('App\Http\Models\User');
}
public function currency_type()
{
return $this->belongsTo('App\Http\Models\CurrencyType', 'currency_type', 'id');
}
}

Answer 1

First thing to improve is in your UserAccountNumber model. Your currency_type relation should be written like:
public function currencyType()
{
return $this->belongsTo(CurrencyType::class, 'currency_type', 'id');
}
Your call would then look like:
// using the currencyType() method from above
$data = UserAccountNumber::with('currencyType')
->orderBy('id', 'DESC')
->paginate(50);
You then can access the currency type in your with with:
#foreach ($data as $key=>$contents)
$contents->currencyType->currency_type
#endforeach

Answer 2

It seems some of the UserAccountNumber do not have currency_type attached to it. Add something like this to your code:
#if (isset($contents->currency_type))
{{ $contents->currency_type->currency_type }}
#endif
Or:
{{ $contents->currency_type->currency_type or 'There is not type' }}
